Composite Higgs: Principles and Application
by Andrea Wulzer (University of Padova & INFN Padova) I will review the theoretical motivations for regarding the observed Higgs as a composite pseudo-Nambu-Golstone boson, and I will illustrate the effective field theory methodologies that can be used to derive the generic phenomenological implications of this idea. For what the LHC experimental program is concerned, the main signatures are moderate deviations of the Higgs coupling from the Standard Model predictions and the direct production of colored fermionic partners of the top quark, the so-called top partners, whose existence is deeply connected with the generation of the Higgs mass. While the precision of coupling measurement is not yet sufficient to draw conclusions, direct top partner searches are already probing the relevant parameter space of Composite Higgs models. There are very good perspectives to observe these states or to exclude their existence by employing the forthcoming 13 TeV LHC data, in the latter case the Composite Higgs scenario will have to be abandoned, at least in its present form.
The Quest for Dark Matter: update and news
by Andrea De Simone (CERN & SISSA & INFN Trieste) I will briefly review the status of Dark Matter searches, in particular indirect searches, and the news from the recently released AMS-02 data. The focus will be then turned to the great relevance of the theoretical improvement of including electroweak radiation effects and how this affects the effective description of Dark Matter interactions. At a phenomenological level, one inevitable consequence of including electroweak corrections is inducing correlations among the predicted particle fluxes targeted by the various experiments. I will describe how the correlations between different data from a single experiment can be used to draw robust conclusions on potential Dark Matter signals.
Mach’s Principle and the Nature of Time
by Esben Mølgaard (DIAS-Universe) The third DIAS Young Scholars Lecture in 2013 is by Esben Mølgaard (DIAS-Universe). The lecture is followed by a small reception.
Is that a Standard Higgs? And now?
by Pierpaolo Giardino (University of Pisa & INFN Pisa) The new particle found at LHC could be the long-waited Higgs boson, so a precise knowledge of its properties is mandatory. Apparently the data are converging toward a Standard Model Higgs, and if that is the case the measured Higgs mass put the SM (and us) in a near-critical situation where the minimum of the EW vacuum is metastable. I will briefly review the status of our understanding of the new found particle properties, then I will focus on the (meta)stability of the EW vacuum, trying to investigate if there are some profound implications for this near-criticality.
Holographic thermalization at intermediate coupling
by Aleksi Vuorinen (Bielefeld University) I will discuss a series of recent works aimed at understanding the thermalization process in N=4 Supersymmetric Yang-Mills plasma outside the usual holographic limit of infinite 't Hooft coupling. It will be demonstrated that accounting for the leading non-trivial terms in a strong coupling expansion has a qualitative effect on the behavior of various off-equilibrium Green's functions near the thermal limit. Based on this, I will argue that the usual top-down pattern of holographic thermalization is modified as the coupling is decreased, and that it eventually shifts to a bottom-up behavior.
The Yang-Mills gradient flow in non-abelian gauge theories
by Daniel Nogradi (Eotvos University) The Yang-Mills gradient flow is a recent addition by Martin Luscher to the arsenal of techniques used in the study of non-abelian gauge theories. After introducing the concept in a pedagogical manner I will use the gradient flow to define a new running coupling scheme in finite volume. This new scheme is then used to calculate the beta-function of SU(3) gauge theory coupled to Nf = 4 flavors of fundamental fermions. The calculation is non-perturbative and is done by lattice discretization. A careful and controlled continuum limit is taken at the end.
Rotational & magnetic field instabilities in neutron stars and their constraints in the equation of state
by Kostas Kokkotas (Universität Tübingen) We will review the theory of neutron star instabilities due to the presence of strong magnetic fields or fast rotation. We will present the latest results in the framework of general relativistic theory, their importance for the gravitational wave detection but also their signatures in the electromagnetic spectra (gamma & x-rays). Finally, we will demonstrate how we can use these observations in constraining the neutron star equation of state.
Dark World
by Zurab Berezhiani (Università degli Studi de l'Aquila & LNGS) I will discuss scenarios in which dark matter emerges as a matter of some hidden gauge sector, with microphysics similar or exactly same as that of ordinary particles. I will show that B-L violating interactions between the particles of ordinary and hidden sectors can give rise to a baryogenesis/leptogenesis scenario that co-generates both ordinary and dark matters in proper proportions. Second, these interactions can lead to particle mixing phenomena between two sectors (neutrinos, neutrons, etc.) which can be tested at small scale experiments. Third, such interactions can be interesting in view of dark matter direct detection.
Neutrino Mass and Dark Matter
by José W. F. Valle (Instituto de Física Corpuscular Univ. de Valencia-CSIC) I will review the status of neutrino mass and mixing parameters, theoretical modeling and cosmological implications. In particular discuss how neutrino mass and dark matter may be closely connected and indicate possible direct, indirect and collider detection prospects.
Thermal decoupling in WIMP dark matter models with long-range interactions
by Torsten Bringmann (University of Hamburg) The chemical decoupling of weakly interacting massive particles (WIMPs) in the early universe determines their relic density today. Kinetic decoupling, on the other hand, happens only considerably later and sets a scale that can directly be translated into a small-scale cutoff in the spectrum of matter density fluctuations, corresponding to the least massive protohalos that can form. In models where the WIMPs are subject to a long-range interaction mediated by a light force carrier, these two processes in general cannot be separated anymore. A rich phenomenology results, ranging from a potentially new era of dark matter annihilation around and after kinetic decoupling to much larger cutoff masses than for standard dark matter candidates like the MSSM neutralino. In this talk, I will review the formalism that allows to calculate both the chemical and kinetic decoupling process to a high precision even in this case. As an application, I will illustrate the main differences to the standard case in terms of simple toy models and demonstrate that such models might even provide a simultaneous solution to all small-scale problems of LambdaCDM cosmology.
Smoking gun or damp squib? Gamma-ray lines in the Fermi LAT data
by Christoph Weniger (GRAPPA Institute) The observation of a gamma-ray line at the Galactic center would be a `smoking gun' signature for annihilation of WIMP dark matter particles in the Universe. At energies around 130 GeV, we find first indications for such a line feature in the public data taken by the Fermi Large Area Telescope since 2008. The excess is not inconsistent with a gamma-ray line from dark matter annihilation. If interpreted in terms of dark matter particles annihilating into a photon pair, the observations require a very large partial annihilation cross-section of about 10^-27 cm^3 s^-1. After a general introduction to indirect dark matter searches with gamma rays, we will focus on details and caveats of the statistical analysis, latest developments, a similar feature in the Earth limb, and how the tentative signal will be hopefully either rejected or confirmed in the not too distant future.

Suppressing Quantum Fluctuations in Classicalization
by Alexander Vikman (CERN & Stanford University) Following my recent paper arXiv:1208.3647, I will start by reviewing one of the cornerstones of quantum mechanics uncertainty relations. Further, I formulate the uncertainty relations in QFT. Then I will discuss vacuum quantum fluctuations of simple Nambu-Goldstone bosons derivatively coupled single scalar field theories possessing shift symmetry in field space. I will argue that quantum fluctuations of the interacting field can be drastically suppressed with respect to the free field case. Moreover, the power-spectrum of these fluctuations can soften to become red for sufficiently small scales. In quasiclassical approximation, it is demonstrated that this suppression can only occur for those theories that admit such classical static backgrounds around which small perturbations propagate faster than light. Thus a quasiclassical softening of quantum fluctuations is only possible for theories which classicalize instead of having a usual Lorentz invariant and local Wilsonian UV-completion. I will illustrate this analysis by estimating the quantum fluctuations for the DBI-like theories.
Signals from the dark Universe: the DAMA/LIBRA results and perspectives
by Pierluigi Belli (University of Rome "Tor Vergata" & INFN Rome) The DAMA/LIBRA set-up (about 250 kg highly radiopure NaI(Tl)) is running at the Gran Sasso National Laboratory of the I.N.F.N.. The results obtained by exploiting the model independent annual modulation signature for the presence of Dark Matter particles in the galactic halo will be discussed. The data satisfy at high confidence level all the many requirements of the Dark Matter annual modulation signature. Presently DAMA/LIBRA is in data taking in a new configuration equipped with new high quantum efficiency PMTs. Results, implications and experimental perspectives will be addressed.
Nonequilibrium QFT approach to baryogenesis
by Matti Herranen (NBI) The observed baryon asymmetry of the Universe may have been produced dynamically in the very early Universe by a baryogenesis process. Leptogenesis and Electroweak baryogenesis (EWBG) are among the most prominent candidates for a successful baryogenesis. For reliable calculations of the asymmetry first principle methods of nonequilibrium quantum field theory are required. We construct a transport theory of baryogenesis based on the Schwinger-Keldysh or Closed Time Path (CTP) formalism of nonequilibrium QFT. The resulting kinetic equations incorporate finite density medium effects and quantum coherence effects and therefore provide a generalization to standard (quantum) Boltzmann equations. For leptogenesis we find that the finite density corrections from loop integrals typically lead to an enhancement of the asymmetry. In the resonant regime with nearly degenerate right-handed neutrino masses, our results confirm the general structure of the resonant enhancement of CP-violation, however, novel terms related to flavour oscillations can be important in the dynamics. For EWBG we show that quantum coherence effects related to particle-antiparticle (flavour) mixing may have a large effect on the generated asymmetry due to flavour dynamics and quantum reflection from the bubble wall.
Imprints of primordial magnetic fields on the CMB
by Kerstin Kunze (University of Salamanca) Magnetic fields are observed on nearly all scales in the universe, from stars and galaxies upto galaxy clusters and even beyond. The origin of cosmic magnetic fields is still an open question, however a large class of models puts its origin in the very early universe. Observations of the cosmic microwave background (CMB) provide a window to the early universe and might therefore be able to tell us whether cosmic magnetic fields are of primordial, cosmological origin and at the same time constrain its parameters. I will discuss the effects of a stochastic helical magnetic field on the scalar, vector and tensor perturbations and present the resulting angular power spectra of the CMB temperature anisotropies and polarization.
A non-Gaussian landscape
by Sami Nurmi (University of Helsinki) Primordial perturbations with wavelengths greater than the observable universe shift the effective background fields in our observable patch from their global averages over the inflating space. This leads to a landscape picture where the properties of our observable patch depend on its location and may significantly differ from the expectation values predicted by the underlying fundamental inflationary model. I will demonstrate that if multiple fields are present during inflation, this may happen even if our horizon exit would be preceded by only a few e-foldings of inflation. Non-Gaussian statistics are especially affected: for example models of local non-Gaussianity predicting |f_NL| >> 10 over the entire inflating volume can have a probability up to a few tens of percent to generate a non-detectable bispectrum in our observable patch |fNL^{obs.}| <10. I will explore the connection between the observable local primordial perturbations and global properties of the inflating space which reflect the underlying high energy physics. I will discuss the implications of both a detection and non-detection of primordial non-Gaussianity by Planck, and provide new insights on the naturalness of different observational configurations.
Bayesian forecasts from Dark Matter Direct Detection to LHC
by Giorgio Arcadi (QFT Uni Göttingen) The complementarity between different strategies of Dark Matter search is a powerful tool for identifying the DM microscopic properties and its importance is growing in perspective of the next future update of LHC and of the onset of next generation Dark Matter Direct Detection (DD) experiments. I will discuss a strategy for combining DD and collider searches. Adopting as working framework the Minimal Supersymmetric Standard Model (MSSM), a method for translating the information encoded in an hypothetically discovered DD signal into classes of expected signals at LHC will be proposed. For illustrative purposes I will discuss the application of this method to some benchmark scenarios. The result obtained are regarded as a first step towards the development of a strategy to systematically translate a direct detection signal into a prediction for the LHC.
Holography and the Quark-Gluon Plasma
by Francesco Bigazzi (University of Florence & INFN Pisa) In highly energetic collisions of heavy ions, a novel state of matter, called quark-gluon plasma, is produced. Data collected at the Relativistic Heavy Ion Collider and at LHC, suggest that the plasma behaves like a nearly ideal liquid and thus that it is inherently strongly coupled. Understanding its dynamical properties is very challenging for theoretical physics. Holographic techniques, mapping strongly coupled quantum field theories to weakly coupled higher dimensional theories of gravity, could help in providing novel complementary tools. After providing a short general introduction to these techniques I will focus on some applications to Quark-Gluon plasma models, focusing on flavor effects, thermodynamics and transport properties.

Some possible consequences of the huge magnetic fields generated at the LHC
by Poul Olesen (NBI) The usual comparison between the electroweak part of the standard model and the new experimental results from the LHC ignores the huge, but short lived, magnetic field that is generated during a proton-proton collision. We explain the phenomenon of W condensation, which can occur as a consequence of the magnetic field. This would among other things have an effect on the rate Higgs -> two photons, where preliminary data indicate a deviation from the perturbative rate. We also point out that even if W condensation does not occur, these perturbative calculations should be modified as a consequence of the large magnetic field which influence the relevant W propagators.
QCD resummation techniques applied to beyond the standard model physics
by Benjamin Fuks (University of Strasbourg) When studying the transverse-momentum (pT) distribution of a produced colorless final state, it is convenient to separate the large- and small-pT regions. For the large values of pT, the use of the fixed-order perturbation theory is fully justified, but in the small-pT region, the coefficients of the perturbative expansion are enhanced by powers of large logarithmic terms. Furthermore, at the production threshold, the mismatch between virtual corrections and phase-space suppressed real-gluon emission leads also to the appearance of large logarithmic terms. Accurate theoretical calculations must then include soft-gluon resummation in order to obtain reliable perturbative predictions and properly take these logarithms into account. We present precision calculations for slepton-pair, gaugino-pair and Z’ production at hadron colliders, matching transverse-momentum spectra, invariant-mass distributions and total cross sections obtained with the use of resummation with those obtained through pure perturbative calculations. We compare then the resummed results with those provided by Monte Carlo generators such as MC@NLO, PYTHIA or MadGraph (including a matching a la MLM), and study the impact of scale variations, parton densities, and non-perturbative effects.
Indirect detection of DM – status and prospects
by Martti Raidal (NICPB & CERN) Abstract: I shall review the current status of searches for Dark Matter. I shall put the main focus on indirect searches for Dark Matter and present the most important results obtained by PAMELA and Fermi-LAT experiments. I shall discuss in detail the recent discovery of 130 GeV gamma-ray line in Fermi-LAT data and show its implications for our understanding of DM properties.

Gauge dynamics in non-equilibrium plasmas
by Aleksi Kurkela (McGill University) How do non-equilibrium non-abelian plasmas thermalize? Depending on the initial conditions, the dynamics of the non-equilibrium system is dictated by elastic scattering, inelastic scattering or --- in the case of some anisotropic initial conditions -- plasma instabilities. I will describe these processes in physically transparent way in the weak coupling limit with an emphasis on screening and LPM effect, and present an application to early stages of heavy ion collisions.
Naturalness and enhanced diphoton rate in the GNMSSM
by Kai Schmidt-Hoberg (CERN) We determine the degree of fine tuning needed in a generalised version of the NMSSM that follows from an underlying Z4 or Z8 R symmetry. We find that it is significantly less than is found in the MSSM or NMSSM and extends the range of Higgs mass that have acceptable fine tuning up to Higgs masses of mh ~ 130 GeV. We also study the di-photon rate in Higgs decays within this framework and point out that light charginos as well as a light charged Higgs can significantly contribute to the corresponding partial decay width, allowing for an explanation of the experimental indication whithin a natural supersymmetric model. This is in contrast to the `light stau scenario' proposed within the framework of the MSSM which requires a large amount of electroweak fine tuning. The talk is sponsored by FNU's Sapera Aude Programme.
A lecture on supersymmetry breaking
by Francesco Caracciolo (SISSA, Trieste) It is well known that if supersymmetry has a role in nature then it should be (spontaneously) broken. In this lecture, a series of results related to the classical breaking of supersymmetry will be first given and analyzed and, then, after the exposition of the perturbative non-renormalization theorem, a few comments on dynamical supersymmetry breaking will be done; finally, some relevant phenomenological applications will be considered.

Current and future constraints on neutrinos from large scale structure
by Steen Hannestad (Aarhus University) Some neutrino properties, such as the absolute mass, can be probed very precisely using cosmological data. In the talk I will review how neutrinos influence the formation of structure as well current bounds on neutrino properties, including hypothetical new sterile neutrinos. I will then discuss future structure formation probes, mainly the recently approved ESA mission EUCLID and its potential for probing neutrino physics.
Understanding Collective Adaptation: An Introduction to Cue Learning Psychology
by Ulrik William Nash (DIAS-Organization) The talk is part of the DIAS Young Scholars Lecture Series, and is followed by a small reception. Abstract: We are surrounded by enormous quantities of information which, objectively speaking, has relevance for our performance. Indeed, environments generate much more information than we can possibly use when making decisions and our expectations about environments are inevitably characterized by imperfection. Nevertheless, despite these facts, we undeniably function and achieve. In this Young DIAS Scholar lecture, Ulrik W. Nash will introduce you to a branch of psychology that explains how such function and achievement is nevertheless possible. Drawing on his own research, Ulrik will demonstrate the relevance of this branch of psychology for understanding individual and collective adaptation.

Testing the initial conditions with the Large-Scale Structure of the Universe
by Emiliano Sefusatti (ICTP) The possible detection of a non-Gaussian component in the initial condition of the Universe could provide crucial information on the physics of inflation. While current constraints on non-Gaussian parameters are still consistent with the Gaussian hypothesis, the Planck satellite will soon significantly improve these limits. In case of detection, a confirmation from different observables, as the for instance the galaxy distribution, will be required. I will review the basic effects of non-Gaussian initial conditions on the evolution of the large-scale structure of the Universe, paying specific attention to how they affect the nonlinear growth, both of the matter power spectrum and higher-order correlation functions as well as the corrections induced to linear and nonlinear galaxy bias. In addition, I will present the case of the Quasi-Single Field model of inflation, characterized by a quite rich phenomenology in terms of its observational consequences.
Effective CP-violation in the Standard Model
by Anders Tranberg (NBI) The observed asymmetry between matter and antimatter is expected to originate from physics at or beyond the electroweak scale in the very early Universe. Standard lore tells us, that the CP-violation present in the Standard Model is insufficient to account for the magnitude of the asymmetry. We compute of the effective CP-violation arising from integrating out the fermions at finite temperature, to leading order in a gradient expansion. We confirm standard lore at electroweak temperatures, but not at temperatures around 1 GeV.
Non-perturbative decay of the curvaton into Higgs
by Rose Lerner (Helsinki Institute of Physics (HIP)) Abstract: In an inflationary cosmology, the observed primoridal density perturbation could come from the quantum fluctuations of another light 'curvaton' field, rather than the inflaton. We investigate a simple model where the curvaton is coupled only to the Standard Model Higgs boson. In such case, one would expect a fast non-perturbative decay of the curvaton, so that the curvaton would not have time to build up the curvature perturbation. However, we find that, contrary to expectation, the curvaton decay may be delayed even down to electroweak symmetry breaking. This happens because of thermal corrections to the higgs mass due to the thermal background generated by the inflaton decay. As a consequence, it is possible to obtain the observed curvature perturbation for a wide range of parameters.

Holographic thermalization – an update
by Michal Heller (University of Amsterdam) For the last couple of years applications of AdS/CFT correspondence has been among the most popular research trends. The field kicked off with the calculation of the shear viscosity of the plasma of N=4 SYM theory, famous η/s = 1/4π. This surprisingly small number turned out to be very close to values needed to describe hydrodynamic part of the evolution of the quark-gluon plasma in heavy ion collisions at RHIC and LHC experiments, yet it is not known how to obtain it from first principle calculations in QCD. In my talk I will give an overview of how AdS/CFT correspondence can contribute to understanding another puzzle in heavy ion collisions, the very short time, of order of 0.5 fm/c, it takes there to reach hydrodynamic regime. The talk will be partly based on arXiv:1103.3452 and arXiv:1202.0981.
Soft Gravitons Screen Couplings in de Sitter Space
by Hiroyuki Kitamoto (KEK) The scale invariance of the quantum fluctuations in de Sitter space leads to the appearance of de Sitter symmetry breaking infra-red logarithms in the graviton propagator. We investigate how virtual gravitons of the super-horizon scale affect the local dynamics of matter fields at sub-horizon scale. We show that the IR logarithms do not spoil Lorentz invariance in scalar, Dirac and gauge field theories. The leading IR logarithms can be absorbed by time dependent wave function renormalization factors. In the interacting field theory with λϕ4, Yukawa and gauge interactions, we find that the couplings become time dependent with definite scaling exponents. We argue that the relative scaling exponents of the couplings are gauge invariant and physical as we can use the evolution of a coupling as a physical time.
Exclusive photoproduction and gamma-gamma processes at the LHC
by Wolfgang Schäfer (Institute of Nuclear Physics, PAN, Poland) In central exclusive and central diffractive production we study very special events, in which the incoming protons emerge intact in the final state and are scattered into very small angles. Additional particles are produced at central rapidities, separated by large rapidity gaps from the outgoing protons. The relevant production mechanisms for this final state topology are connected with various t-channel exchanges, most notably Pomeron-Pomeron fusion, γ-Pomeron fusion (or photoproduction) and γ-γ-fusion. I will discuss recent results concerning the exclusive central photoproduction of vector mesons. Recently our knowledge on vector meson photoproduction has been furthered by experiments at the HERA accelerator. These experiments have been a testbed of ideas on the production mechanism, the QCD Pomeron exchange. I will show how exclusive production at the LHC will allow us to access photoproduction at still higher energies. The physics spectrum that can be studied with exclusive processes is quite broad, and I will also discuss the possibilities to constrain physics beyond the Standard Model by measuring e.g. exclusive W+ W- production via γ-γ fusion.

Cutoffs, Stretched Horizons and Black Hole Radiators
by Nemanja Kaloper (UC Davis, California) We argue that if the UV cutoff of the IR theory is of the order, or below, the scale of the stretched horizon in a black hole background, which in turn is significantly lower than the Planck scale, the black hole radiance is controlled by the UV completion of the field theory. In particular, if the UV completion of the theory involves degrees of freedom which cannot be efficiently emitted by the black hole, the naive radiance rate estimated by the counting of the IR degrees of freedom may be dramatically reduced. If we apply this argument to the RS2 brane world, it implies that the emission rates of the low energy CFT modes will be dramatically suppressed: its UV completion is given by the bulk gravity on $AdS_5 \times S^5$, and the only bulk modes that could be emitted by a black hole are the s-waves of bulk modes with small 4D masses. But their emission is suppressed by bulk warping. This lowers the radiation rate much below the IR estimate, and follows directly from low CFT cutoff $\mu \sim L^{-1} \ll M_{Pl}$, a large number of modes $N \gg 1$ and the fact that 4D gravity in RS2 is induced, $M_{Pl}^2 \simeq N \mu^2$.
Effective Field Theory in Inflation
by Mark Jackson (University of Paris 7) Although the observed CMB is at very low energy, it encodes ultra high-energy physics in spatial variations of the photon temperature and polarization fluctuations. This effect is believed to be dominated by the initial quantum state of the Universe. I will describe the first theoretical tools by which to construct such a state from fundamental physics. One can then use this technique to reliably calculate corrections to the power spectrum, non-Gaussianity, etc from high-energy physics. We may soon be able to compare these predictions against experiment, allowing one to rule out classes of quantum gravity models. Now is the critical time to undertake such investigations, with a number of ongoing and planned experiments such as Planck and CMBPol/Inflation Probe poised to collect a wealth of precision data.
Liquid Helium and QCD: Feynman’s Last Problem
by V. Parameswaran Nair (City College of CUNY) In 1954, Feynman gave a beautiful analysis of superfluid Helium using general properties of wave functions and of the space of particle configurations. In the 1970s, starting with the discovery of asymptotic freedom and the emergence of QCD, the question of quark confinement and the generation of a mass gap was recognized as an important question about the nonperturbative behavior of nonabelian gauge theories. Needless to say, this has proved to be a very difficult problem to analyze. Two spatial dimensions would provide the simplest case of a nontrivial gauge theory which could exhibit confinement and mass gap. In 1981, Feynman tried to use a set of arguments similar to what he had developed for superfluidity to argue for the existence of a mass gap for these theories. Did he succeed? Did he fail? If so, to what extent?
QCD in the era of the LHC: Theory and Practice
by Peter Skands (CERN) Cosmic Rays, Dark-Matter annihilation, and LHC collisions have one thing in common: production and fragmentation of coloured particles at extremely high energies. Solutions to these phenomena are currently heavily based on semi-classical approximations, from leading-order, leading-color, and leading-logarithmic approximations on the perturbative side, to the use of classical 1+1-dimensional string models on the non-perturbative one. I will review the current state of the art of these approximations, from small to large distances, and discuss ways of putting the "Quantum" back in QCD.
Cosmology in our backyard
by Carlos Frenk (Durham University) The LCDM cosmological model accounts for an impressive array of data on the large-scale structure of the universe. On submegaparsec scales, however, the model cannot be tested with the same degree of rigour as on larger scales where microwave background radiation data and measures of galaxy clustering provide clean and well-understood diagnostics. Yet, it is precisely on these small scales that the nature of the dark matter manifests itself most clearly. I will discuss theoretical predictions for the small-scale structure of the universe which appear to be discrepant with recent kinematical data for satellite galaxies of the Milky Way. Possible solutions range from exotic baryonic processes to the more radical assumption that the dark matter is not what the standard theory assumes.
Lattice Artifacts in Strongly Interacting Theories
by Pol Vilaseca (School of Mathematics, Trinity College Dublin) Viable candidate models of Dynamical Electroweak Symmetry Breaking must display a quasi-conformal scaling behaviour in order to accomodate experimental constraints. The scaling properties of a theory can be studied using finite volume renormalization schemes. From these, the most practical ones are based on the Schrodinger Functional (SF). However, SF schemes suffer from potentially large O(a) effects and special care has to be taken to remove these effets. Here we will compare the standard setup of the SF with Wilson quarks to a setup with chirally rotated boundary conditions (χSF). We study the O(a)-improvement of both setups at 1-loop in perturbation theory, and we prescribe a way of minimizing higher order cutoff effects.
Flavour Physics in the LHC Era
by Andrzej Buras (Technical University of Munich, Germany) This decade should provide a much better understanding of the physics at the shortest distance scales explored by humans, that is scales of order $5\times 10^{-20}$m explored by ATLAS and CMS and possibly even shorter distance scales explored by dedicated flavour physics experiments like LHCb, SuperKEKB, SuperB in Rome and Kaon physics dedicated experiments like NA62, ${\rm K^0}$TO and ORCA. The main goal of these experiments is the search for New Physics (NP) in weak decay processes. The goal of this talk is to provide a grand picture of this fascinating field and to discuss various NP scenarios beyond the Standard Model and various ways they could be tested through flavour violating processes. The very recent data from the LHCb had a significant impact on various NP models. For some models the LHCb data turned out to be a relief, for other a problem. I will present the first assessment of the impact this data has on our understanding of flavour physics.
Puzzles of Dark Matter Searches in the Light of Dark Atoms
by Maxim Khlopov (APC Paris VII) Direct searches for dark matter lead to serious problems for simple models with stable neutral Weakly Interacting Massive Particles (WIMPs) as candidates for dark matter. A possibility is discussed that new stable quarks and charged leptons exist and are hidden from detection, being bound in neutral dark atoms of composite dark matter. Stable -2 charged particles O^{--} are bound with primordial helium in O-helium atoms, being specific nuclear interacting form of composite dark matter. The positive results of DAMA experiments can be explained as annual modulation of radiative capture of O-helium by nuclei. In the framework of this approach test of DAMA results in detectors with other chemical content becomes a nontrivial task and the O-helium solution for the puzzles of dark matter searches is possible.
Light scalar mesons
by Joseph Schechter (Syracuse University) The Higgs sector of the electroweak theory has been a problem since 1967. The Higgs sector of ordinary QCD has been a problem since about 1960. Where do things stand today?
Exploring the QCD phase diagram by lattice simulations
by Massimo D'Elia (University of Pisa, Italy) We review the present status of our knowledge about the structure of the phase diagram of strong interactions, as it emerges from lattice QCD simulations.
Flavor Physics: Past, Present, Future
by Yosef Nir (Weizmann Institute of Science, Rehovot, Israel) Experimental measurements in the B factories have led to significant progress in our understanding of flavor physics and the related CP violation. Yet, two questions remain open: First, if there is new physics at the TeV scale, why hasn't it been manifest in flavor changing processes? Second, what is the source of the smallness and hierarchy in the standard model flavor parameters? The ATLAS and CMS experiments can provide unique ways of answering these puzzles.
Dark Matter in Extra Dimensions: a tale on the Real Projective Plane
by Giacomo Cacciapaglia (Lyon, IPN) The compactification of extra dimensions may lead to conserved parities on the effective 4-dim models, thus offering a natural Dark Matter candidate. I will discuss how un-generic this feature is, and how it can be efficiently used to select interesting orbifolds for model building. Finally, I will briefly describe the LHC phenomenology of the minimal case in flat space. the Real Projective Plane.
Bounding Light Higgs
by Alexander Azatov (INFN, Rome) I will present up-to-date constraints on a generic Higgs parameter space. I will show how one can use the data reported by the experimental collaborations to constrain in a statistically accurate way couplings of the Higgs like scalar. At the end I will discuss the bounds on these couplings coming from most recent LHC results.
Dark Matter Phenomenology
by Thomas Schwetz (Max Plank Institute, Heidelberg) After reviewing the evidences we have for dark matter in our Universe I discuss particle physics solutions to this problem, focusing on Weakly Interacting Massive Particles (WIMPs) in a model-independent way. I present production mechanisms of dark matter candidates in the early Universe as well as possible experimental tests of the WIMP hypothesis including collider experiments, indirect and direct detection of WIMPs. Emphasis will be given on the phenomenology of the direct search for dark matter particles in underground detectors, and implications of recent experimental results are discussed.
Coloron production at NLO: techniques and results

1st CP3 meeting on ethics and responsible conduct in research
by Dominique Bouchet Professor Dominique Bouchet from the Department of Marketing and Management, SDU, will give a seminar introducing the ethical implications of being researcher and the consequences of misconduct in research. Science and scientific research have, today more than ever, a huge impact on society, culture, and on the way people perceive themselves and the reality around them. For this reason, scientists have big responsibilities and must perform their work as fairly as possible. Any negligence could have enormous consequences on other researcher’s work and on technology development, it causes financial losses and it constitutes a threat to the level of thrust attributed to research in general. Recently the media focused on a serious case of misconduct in scientific research that happened in Denmark, involving falsification of research data. Although being an extreme behaviour, intentional acts like these do not exhaust the list of possible negligences in research. In fact sometimes people do wrong even when they do not mean to, just because they are not properly aware of the implications and consequences of their behaviour. We decided therefore to go deeper in our understanding of the implications of our job, to get more self-awareness and work in a more responsible and conscious way. See also the related news for further details.
Conformal invariance of primordial perturbations
by Paolo Creminelli (ICTP, Trieste) Primordial perturbations are (approximately) scale-invariant. I discuss the conditions for this symmetry to be promoted to the full conformal group and the role of non-linear realized conformal symmetry.
Topological susceptibility and axial symmetry at finite temperature
by Guido Cossu (KEK Theory Center) We consider the simulation of finite temperature QCD with two flavors of dynamical overlap fermions in order to study the suppression of the axial U(1) symmetry breaking at the chiral phase transition point. As a preliminary study, pure gauge simulations are performed to investigate how fixing the topology affects physical quantities like the topological susceptibility, at finite temperature, showing that it is possible to reconstruct known results from the fixed topology sector. First results on the degeneracy of meson correlators in the high temperature QGP sector are shown.
Grand Unification: the quest for the minimal theory
by Luca Di Luzio (Karlsruhe Institute of Technology) We provide a pedagogical introduction to the field of grand unification focusing the attention on proton decay and neutrino masses. Despite the huge amount of work done since the seminal paper of Georgi and Glashow, no theory of grand unification has clearly emerged so far. In this respect we emphasize the role of minimality as a guiding principle in order to discriminate among models and eventually falsify them. Sticking to the SO(10) case minimality is closely related to the complexity of the Higgs sector. We finally review some recent results on the spontaneous symmetry breaking of SO(10) GUTs.
Indirect detection of unstable dark matter
by Alejandro Ibarra (Technische Universität München) Present evidence for dark matter in our Galaxy and in the Universe at large does not exclude the possibility that the dark matter particles could be unstable. If this is the case, their decays into positrons, antiprotons or gamma rays might occur at rate sufficiently large to allow the indirect dark matter detection through an anomalous contribution to the high energy cosmic-ray fluxes. We discuss in this talk the constraints on the dark matter lifetime from various observations and the prospects for future detection.
Probing fundamental physics with primordial non-Gaussianity
by Martin S. Sloth (CERN, Theoretical Physics Division) We will discuss what can be learned about fundamental physics and the origin of the universe if primordial non-Gaussianity is observed by the European Planck satellite.
Status of Indirect Dark Matter Detection
by Pasquale Serpico (LAPTh, Annecy-Le-Vieux) Indirect astrophysical channels such as gamma rays, neutrinos, cosmic ray antimatter remain a cornerstone for the dark matter particle identification program. In the first part of the talk a review of the present indirect constraints on dark matter will be given. In the second part, I'll focus on the importance of accounting for astrophysical backgrounds, when moving from setting constraints in parameter space to the more challenging ambition of detection. Barring some exception, we are close to the limits of blind searches for indirect dark matter due to systematic limitations to our understanding of astrophysical backgrounds. I will advocate a change of perspective in these searches, where guidance from collider and direct detection programs is exploited to perform a much more fruitful "a priori" search for correlated signatures in many indirect channels.

Phenomenology of the 4-site Higgsless model at the LHC
by Elena Accomando (University of Southampton) The Large Hadron Collider (LHC) at CERN is performing beyond expectations. It has already accumulated 1 fb-1 of luminosity and in one year from now it is expected to reach 10 fb-1. LHC will be thus ready to answer the main question in particle physics: what is the ElectroWeak Symmetry Breaking mechanism (EWSB) which gives mass to our world? The Standard Model and its Supersymmetric extension predict the existence of fundamental Higgs bosons triggering EWSB. Hence, most of the experimental effort is naturally devoted to Higgs boson discovery. However, in the negative case, testable alternative formulations of EWSB must be ready to be searched for. Amongst these, we focus here on the 4-site Higgsless model which merges elements of both Technicolor and extra dimensions. We discuss its phenomenological aspects, and show the reach for both exclusion and possible observation in one-year time of the LHC data taking.
Inflation
by Fedor Bezrukov (University of Munich) Abstract: I will review the model, where the inflationary expansion of the Universe is caused by the Standard Model Higgs field non-minimally coupled to gravity. I will argue that the region of applicability of the model is defined by the background dependent cut-off scale, which is high during inflation. I will formulate additional requirements on the "full" theory, that are required for successful quantum analysis during the inflationary epoch. I will also describe a set of phenomenological consequences that may follow from the model with background dependent cut-off scale.
Scaling behavior of strongly-flavored gauge theories
by Jens Braun (University of Jena) Abstract: The existence of universal behavior plays a very important role in modern physics since it allows us to classify theories according to their scaling behavior close to a critical point. In this talk, we analyze the scaling behavior of physical observables in strongly-flavored asymptotically free gauge theories, such as many-flavor QCD. Such theories approach a quantum critical point when the number of fermion flavors is increased. Close to this critical point, physical observables then exhibit an exponential scaling behavior, provided the gauge coupling is considered as a constant external parameter. We discuss how this exponential scaling behavior is modified when the scale dependence of the gauge coupling is taken into account. In particular, we present estimates for the size of the regime with an exponential scaling behavior in QCD with $N_f$ fermion flavors and $N_c $ colors. Our results suggest that the corrections to the exponential scaling behavior might be relevant for the analysis of lattice QCD data.
The effective W approximation for WW scattering and new physics
by Roberto Franceschini (EPFL Lausanne) In this talk I review the motivations and the prospects of the study of the scattering of W boson. The details of the mechanism of electroweak symmetry breaking (EWSB) that can be unveiled studying WW scattering will be presented. The issue of the extraction of on-shell WW -> WW scattering amplitudes from the study of physical processes initiated by fermions, i.e. qq -> qqWW, will be addresses using the effective W approximation (EWA). A discussion of the regimes of validity and of the expected corrections to the EWA will be presented together with a detailed comparison of the EWA to existing MC and analytical computations.
Flavour Physics Beyond the Standard Model
by Federico Mescia (University of Barcelona) I will present a summary of what we learned so far from low-energy flavour-quark observables, concerning physics beyond the Standard Model (SM). In the last few years there has been a great experimental progress in quark and lepton flavour physics. In the quark sector, the validity of the SM has been strongly reinforced by a series of challenging tests. More important, several suppressed observables (such as DMBs, sin(2beta), epsK, b->sgamma) potentially sensitive to New Physics (NP) have been measured with good accuracy, showing no deviations from the SM. In constructing a realistic SM extension we should then try to reconcile many non-trivial constraints. The Minimal Flavour Violation hypothesis well handles flavour-quark data and shows, in the large tanbeta scenario, interesting effects to be detected by LHCB.
Dark Energy and the Cosmological Constant Problem
by Florian Bauer (Barcelona University) Abstract: The currently observed acceleration of the universe may originate from "dark energy", a new component in the energy content of the cosmos. A tiny positive cosmological constant would be the simplest solution, however, it is usually rejected because our well-working particle physics theories suggest a much larger magnitude than observed. Therefore, other sources of acceleration have been considered, e.g. scalar fields, modified gravity, back reaction effects or a misinterpretation of observations. In these setups the cosmological constant is usually set to zero, and the problem is ignored. Different from that, I will discuss some scenarios that aim at providing low curvature solutions despite the existence of a large cosmological constant.

Sannino on DK4
As part of a series on Eliteforskerne (winners of the Danish Elite Researcher Prize) the director of CP3-Origins, Francesco Sannino, was interviewed by the Danish TV channel DK4. The series deals with research in general both in a Danish and international perspective, and also gives an overview of the research done by each winner of the Elite Researcher Prize in 2010. Sannino received the prestigious Danish Elite Researcher award in the beginning of 2010. You can read more on the Elite Researcher Prize here. More information on the series of interviews can be found on the homepage of DK4. You can also watch the interview below::
Supersymmetry on the Lattice
by Simon Catterall (Syracuse University & CP3-Origins) Abstract: I will describe a new lattice formulation of N=4 SYM which has the merit of preserving one exact supersymmetry for non-zero lattice spacing. This exact supersymmetry ensures that the only counterterms needed in the lattice theory correspond to renormalizations of existing terms in the bare lattice action. A one loop calculation reveals that the lattice theory requires no fine tuning to target the continuum N=4 theory as the lattice spacing is reduced to zero. The strong coupling regime can be probed using the same Monte Carlo techniques used in lattice QCD.
Conformal Technicolor from Weak Scale SUSY
by Jamison Galloway (University of Rome - Sapienza) Abstract: I will discuss conformal technicolor and some of its possible UV completions. After reviewing the minimal implementation of this idea, I will describe current work where EWSB is shared between a composite sector and that of an elementary SUSY Higgs in a way that allows a new solution to the Higgs mass problem of the MSSM. Here, SUSY breaking itself triggers the phase transition of the strong sector, and a VEV for the elementary fields is consequently induced allowing them to contribute to the masses of the W and Z. The confinement scale can thus be significantly lower than in traditional technicolor, allowing a realistic precision electroweak fit, and suggesting several sub-TeV states that could be easily uncovered at the LHC.
Topics in Lattice QCD and Lattice BSM
by Randy Lewis (York University) Abstract: Three topics will be discussed briefly: the Omega_b baryon mass puzzle, an issue for strongly-coupled Wilson fermions, and spontaneous symmetry breaking in a two-doublet Higgs model.
Supersymmetric Flavour Problem
by Stefan Pokorski (Warsaw University) Abstract: Theories of fermion mass hierachies generate new sources of FCNC and CP violation. When combined with solutions to the gauge hierachy problem, they are strongly constrained phenomenologically. The problems one is facing and potential solutions to them will by discussed in the framework of supersymmetric theories.
Asymptotically Safe Gravity
by Daniel Litim (University of Sussex) Abstract: Three of the four fundamental forces of Nature are successfully described by local quantum field theories. But what is up with gravity? It is well known that the standard quantisation programme for gravity faces problems, and one may wonder whether a quantum field theoretical description is possible at all. In this talk, the scenario of asymptotic safety is explained, according to which gravity achieves a non-trivial fixed point at high energies. Some strong indications for asymptotic safety are reviewed, together with implications for eg. the physics of black holes and high-energetic particle scattering.
Testing SO(10)-Inspired Leptogenesis with Low Energy Neutrino Experiments
by Pasquale Di Bari (Southampton University) Abstract: After reviewing the current status of leptogenesis, we discuss a clear example of how, contrarily to common generic negative statements, a traditional thermal leptogenesis scenario at very high energy scales can leave an imprint on the low energy neutrino parameters when this is embedded within minimal SO(10) models. Therefore, we show how future low energy neutrino experiments can interestingly test scenarios of leptogenesis within grandunified models.
CP3 Mini-Course: An Overview of String Theory
by Paolo Di Vecchia (NORDITA) Abstract for the three lectures: 1) Starting from the string action, I will deduce the spectrum and the scattering amplitudes and from the scattering amplitudes the low energy effective actions: supergravity in the bulk and Dirac-Born-Infeld on the boundary. 2) Compactification on a circle and T-duality that implies both Neumann and Dirichlet boundary conditions for open strings. Compactification of the six extra dimensions and moduli problem. 3)Intersecting and magnetized D branes for constructing string extensions of the Standard Model.
CP3 Mini Course on Cosmology and Inflation
by Anders Basbøll (University of Sussex) Abstract: I review Big Bang Cosmology (ie basic cosmology without inflation), look at the best model we have: ΛCDM (A universe of matter and radiation as we see it and a Cosmological Constant and Cold Dark Matter – the new ingredients carrying more than 95% of the energy in the universe). The homogeneity of the Universe and the fact that the perturbations in energy density are nearly scale invariant points to Cosmological Inflation, a phase of exponential expansion of space in the early universe. First I look at different inflation models with a particle generically known as the Inflaton. Later I look at specific particle physics models that have a particle which can be the inflaton incorporated.
Semiclassical Approaches to IR Issues in Quasi de Sitter Universes
by Martin S. Sloth (CERN) Abstract: Using simple semiclassical relations it is possible to show that the conventional cosmological correlation functions are affected by significant IR corrections in quasi de Sitter space-times when averaged over very large volumes (in the "large box"). The IR effects apparently imply a breakdown of perturbation theory in the large box on sufficiently long time scales, for example the time between self-reproduction and reheating in chaotic inflation. An interpretation of the apparent breakdown of the perturbative expansion of gravity will also be discussed.
CP3 Mini Course on D-branes in String Theory
by Rodolfo Russo (Queen Mary, U. of London) Abstract: The aim of these lectures is to provide an introduction to D-branes in type II string theories. I will start from the basic definition of D-branes as the objects supporting the fundamental string endpoints, then I will describe them from the closed string point of view and I will discuss their "gravitational" backreaction. I will conclude by giving a brief overview on how D-brane bound states have been used to model black holes in string theory. Lecture I Lecture II Lecture III
Seeing Signals of Dark Matter in Cosmic Rays?
by Marco Cirelli (CERN) ABSTRACT: Dark Matter constitutes more that 80% of the total amount of matter in the Universe, yet almost nothing is known about its nature. A powerful investigation technique is that of searching for the products of annihilations of Dark Matter particles in the galactic halo, on top of the ordinary cosmic rays. Recent data from the PAMELA and FERMI satellites and a number of balloon experiments have reported unexpected excesses in the measured fluxes of cosmic rays. Are these the first direct evidences for Dark Matter? If yes, which DM models and candidates can explain these anomalies and what do they imply for future searches? What are the constraints from other gamma rays measurements and cosmology?
Towards the Detection of Cosmological Relic Neutrinos with Neutrino Capture on Beta Decaying Nuclei
by Marcello Messina (Bern University) Abstract: The topic of the seminar will be on a novel idea for the detection Cosmological Relic Neutrinos (CRN) and more in general, for the detection of neutrinos of vanishing energy. This idea is described in detail in the paper [1]. The method is based on the fact that neutrino interactions on beta-instable nuclei have the key feature of requiring no energy threshold for the neutrino interaction. Furthermore, in reference [1] a very interesting feature of v is shown for neutrino interacting with beta-instable nuclei: even if the kinetic neutrino energy vanishes v keeps a constant value depending only on the considered target nucleus. This allows, in principle, the detection of neutrinos of vanishing energy. In order to achieve high detection sensitivity one needs for CRNs discovery new developments are necessary in the field of detectors technology. In the seminar I will describe several detection technologies and eventually I illustrate a possible experimental approach for the discovery of the Cosmological Relic Neutrinos. [1] A. Cocco, G.

Black Holes in Elementary Physics
by Gerard ‘t Hooft (Utrecht University) Abstract In Physics, black holes are known as extremely dense forms of matter, of which, from the outside, only the gravitational force can be detected. Astronomers observe such object ate various spots in the Universe. When in laboratories on earth elementary particles are made to collide with the strongest possible force, these collisions are by far not energetic enough to produce black holes. However, we can try to imagine collisions that are so energetic that black holes do form, and then ask ourselves what exactly might happen then. The question is important because it turns out that our theoretical understanding falls short at this point. The gravitational force is so special that all beautiful theories we have today about the particles and the forces between them cannot describe it. Do black holes obey the laws of quantum mechanics? Are black holes also subatomic particles and vice versa? If so, our theories must be revised. This can lead to fundamental new insights about very basic features in physics, and give us new tools to describe space, time, and matter. Professor Gerard 't Hooft Professor Gerard 't Hooft is a theoretical physicist at Utrecht University, the Netherlands. He shared the 1999 Nobel Prize in Physics with Martinus J. G. Veltman for elucidating the quantum structure of electroweak interactions. He was awarded the Lorentz Medal in 1986 and the Spinozapremie in 1995.

Cloudy with certainty of rain: Effects of QCD Radiation on global inclusive variables
by Andreas Papaefstathiou (University of Cambridge) Abstract: "Amongst the many observables that could be of use in the search for New Physics at hadron colliders, those that do not depend on detailed hypotheses about the structure of the final state may be the most suitable for an initial general survey of the high-energy frontier. Quantities of this type have been named global inclusive observables and may present a useful way of determining the scale of the New Physics without detailed reconstruction of the events. I will be presenting work towards understanding the QCD effects on these variables, through all-order resummation, as well as the effects of any invisible particles originating from decays in the hard process. Moreover I will describe a model-based phenomenological method of determining the effects of the so-called`underlying event' on global inclusive variables. This talk is based on work which appeared in arXiv:0903.2013 and arXiv:1004.4762."

The Dark Side of the Universe: from Small to Large
by Martin Sloth (CERN) Abstract: After a brief introduction to cosmology, I will try to shed some light on the dark side of the universe. It has been said that we know a lot about the universe, but understand very little. I will try to explain what we do understand about the primordial phase of inflation that gave birth to our present universe, about dark energy that dominates the energy density of the universe today, and about dark matter that is the dominant form of matter in the universe. Because everything that is large in the universe today origins from something that was once very small, these questions form an intricate link between particle physics and cosmology.
Majorana Spinors

Constraining Dark Matter
by Chris Kouvaris (Brussels U.) Abstract: Dark matter can be constrained via particle physics experiments like LHC, direct search experiments like CDMS, astrophysical and cosmological observations. The input and the interplay of all these different sectors are important in order to understand the nature of dark matter. I am going to argue that astrophysical constraints arising from compact stars can potentially impose severe constraints on dark matter candidates.
Final State Observables for the LHC
by Andrea Banfi (ETH Zürich) Abstract: We describe the general features of hadronic final state at hadron colliders, highlighting the importance of infrared and collinear safety to devise observables that reflect the underlying quark-gluon energy-momentum flow. We then introduce jets and event shapes, the two observables that are mostly used for studies of hadronic final states. We finally discuss the amount of information that can be extracted at the LHC from measurements of event shape distributions.
The Novel World of Quarks and Gluons
by Stanley J. Brodsky (CP³-Origins & SLAC, Stanford) Abstract: One of the triumphs of theoretical physics of the twentieth century was the development of Quantum Electrodynamics (QED), the fundamental theory of electrons and photons. QED not only describes the physics of the atom with extraordinary precision, but also the basic properties of the electron itself. The corresponding problem in particle and nuclear physics is to accurately describe the structure and interactions of hadrons, such as the proton and neutron, in terms of their fundamental constituents: the quarks and gluons of Quantum Chromodynamics (QCD). In this talk I will discuss a number of novel features of QCD such as "color transparency" and "intrinsic charm", phenomena which were unexpected from conventional approaches to nuclear and particle physics. There are also important analogs between atomic and hadronic physics. For example, the light-front methods which underly phenomenology in high energy physics also have remarkable advantages for describing the wavefunctions of atoms in motion. Conversely, the production of relativistic antihydrogen has provided important insight into the conversion of quarks and gluons of QCD into hadrons at the amplitude level. I will also briefly review how mathematical methods based on an extra space dimension brings new insights into fundamental problems in hadron physics.
Low-Energy Baryon Properties
by Willi Plessas (University of Graz) The description and understanding of low-energy baryon properties such as the mass spectra, electroweak form factors, and some selected reaction processes will be addressed. In particular, results calculated in a relativistically invariant framework along constituent quark models will be discussed in view of properties of low-energy quantum chromodynamics and in comparison to experiments as well as lattice calculations. It will be demonstrated that it is most essential to incorporate the symmetries of quantum chromodynamics, remaining after spontaneous breaking of chiral symmetry, and of special relativity. The first minute of the video was cut out because its audio part was missing: we apologize for the inconvenience.
Microscopic spectra at finite lattice spacing
by Kim Splittorff (NBI) Chiral Random Matrix Theory and Chiral Perturbation Theory has given us extremely useful tools to extract physical observables from lattice QCD simulations. For example, it is possible to determine the infinite volume value of the chiral condensate from finite volume simulations of Lattice QCD. The tools are based on exact analytic computations of the distributions of the smallest (microscopic) eigenvalues of the Dirac operator in a finite volume. This talk presents the first results for the low lying microscopic spectrum of the QCD Dirac operator at nonzero lattice spacing. The results open a novel analytical approach to lattice gauge theory at finite lattice spacing and are crucial for establishing a stable domain for numerical simulations

Hadron form factors
by Marc Vanderhaeghen (Mainz) Recent experimental data in elastic electron-nucleon scattering both at low and large momentum transfers will be discussed. The current precision measurements on the nucleon electromagnetic form factors will be used to map out the transverse charge densities in proton and neutron. The framework will be extended to map out charge densities in higher spin systems, such as the deuteron and nucleon resonances. It will be shown how a field theoretic consistent picture emerges both of densities and of the shape of a relativistic many body system.
Perspectives for quarkonium production at the LHC
by Jean-Philippe Lansberg (CPHT, Ecole Polytechnique) I will discuss the various mechanisms potentially at work in hadroproduction of heavy quarkonia at RHIC, Tevatron and LHC energies in the light of computations of higher-order QCD corrections both in the colour-singlet (CS) and colour-octet (CO) channels. Besides, I will discuss new observables meant to better discriminate between these different mechanisms, including associated production and correlation measurements. On the other hand, I will show how the kinematics specific to the J/psi production matters for the extraction of Cold Nuclear Matter effects, e.g. the shadowing of the gluon distribution in nuclei.
Cold Electroweak Baryogenesis from Standard Model CP-violation
by Anders Tranberg (Helsinki) Abstract: The origin of the observed matter-antimatter asymmetry in the Universe must be sought in high-energy processes within the first second after the Big Bang. Scenarios of this "Baryogenesis" within the Standard Model of particle physics has hit two stumbling blocks: 1) CP-violation is too small at high (electroweak scale) temperatures; and 2) the electroweak phase transition is too weak to provide the necessary departure from thermal equilibrium. We consider an alternative scenario, Cold Electroweak Baryogenesis, where the electroweak transition at the same time provides post-inflationary reheating. In this case, neither 1) nor 2) apply, and we demonstrate by direct numerical lattice simulations that the observed asymmetry can be reproduced, including only Standard Model CP-violation.
Higher-Twist Dynamics in Large Transverse Momentum Hadron Production
by Francois Arleo (Annecy, LAPTH) A scaling law analysis of the world data on inclusive large-pT single hadron production in hadronic collisions is carried out. A significant deviation from leading-twist perturbative QCD predictions at next-to-leading order is reported. The observed discrepancy is largest at high values of xT. In contrast, the production of prompt photons and jets exhibits fixed xT-scaling behavior close to the conformal limit, in agreement with the leading-twist expectation. These results bring evidence for a non-negligible contribution of higher-twist processes in large-pT hadron production in hadronic collisions where the hadron is produced directly in the hard subprocess rather than by gluon or quark jet fragmentation. Phenomenological consequences for RHIC and LHC in p-p and heavy ion collisions are discussed in detail.
Twistors, Unitarity and Hidden Symmetries of Amplitudes
by N Emil J Bjerrum-Bohr (NBI) The last couple of years have witnessed many intriguing breakthroughs in the computation and the understanding of the analytic structure of amplitudes in field theories. In this talk we will discuss such new twistor space inspired methods for amplitude computation and see how for example simple results for tree amplitudes can be recycled to give simple results at loop level via unitarity. We will also discuss hidden symmetries in amplitudes in Yang-Mills theory and gravity and discuss how such amplitudes can be related through newly found monodromy and KLT relations.
Semiclassical rigid strings with two spins in AdS₅
by Arne Lykke Larsen (CP³-Origins) I will talk (using speech synthesis) about the recent paper hep-th/0911.2417 (by Tirziu and Tseytlin), on strings with 2 spins in AdS_5. This paper is closely related to our 6 year old paper hep-th/0312184 (by Khan and ALL). First, I will give an introduction to string theory in curved spacetime. Then I will give a short introduction to the Maldacena Conjecture in the most well investigated case AdS(5)xS(5). Then I will go through the paper and finally have some conclusions and outlook.
Seesaw mechanisms of neutrino masses: naturalness, testability and trivialization
by Zhi-zhong Xing (IHEP, Chinese Academy of Sciences, Beijing) After outlining some popular ways to go beyond the standard model so as to generate finite neutrino masses, I focus on several typical seesaw mechanisms and discuss how to get a balance between theoretical naturalness and experimental testability for them. Besides possible collider signatures at the Large Hadron Collider, new and non-unitary CP-violating effects are also expected to show up in neutrino oscillations for most of the TeV-scale seesaw scenarios. Today, however, the seesaw idea is being trivialized by a number of "additive" and "multiple" versions of seesaw mechanisms.
QCD Like Theories at Next-to Next-to Leading Order
by Lu Jie (Lund University) Abstract: We calculated the vacuum-expectation-value, the meson mass and the meson decay constant to next-to-next-to-leading-order in the chiral expansion for QCD-like theories with general N_F degenerate flavours for the cases with a complex representation, a real and a pseudoreal representation, i.e. with global symmetry and breaking patters SU(N_F)_L*SU(N_F)_R -> SU(N_F)_V, SU(2N_F) -> SO(2N) and SU(2N_F) -> Sp(2N_F). Our results should be useful for lattice calculations for dynamical electroweak symmetry breaking and finite baryon density.
From Random Walks to Dark Matter Haloes
by Antonio Riotto (CERN & Padua) In the current cosmological theory large-scale structures grew via gravitational instability from small-amplitude density fluctuations generated in the very early Universe. Dark matter haloes condense out of these initial fluctuations. This process can be studied by N-body simulations, but it is important to be able to understand the results in simpler terms. We describe a method which is based on the path-integral formulation of field theory to compute the dark matter distribution and is mapped into the so-called first-passage time problem of a random walk in the presence of a barrier. We show that the resulting halo mass function is in remarkable agreement with the existing simulations, without any ad hoc coefficients.
S(3) Symmetry behind Quark and Lepton Masses and Flavor Mixing
by Zhi-zhong Xing (IHEP, Chinese Academy of Sciences, Beijing) Abstract: Current experimental data indicate that the spectra of "bright" masses shouldn't be anarchical. We conjecture that the S(3) flavor permutation symmetry and its breaking might provide a simple way to understand the wide mass gaps between top, bottom, tau and their lighter counterparts, the narrow gaps of three neutrino masses, the smallness of three quark mixing angles, and the largeness of two lepton mixing angles. Could one stone really kill four birds?
Supersymmetric Dark Matter
by Laura Covi (DESY) We will review the particle properties required for a Dark Matter candidate and then discuss possible supersymmetric candidates, with special attention to the gravitino. We will also outline the connection between the different scenarios and the SUSY breaking mediation mechanisms and the related supersymmetric spectra. Finally, we will mention the expected signals at colliders and in DM searches.
Higgs in Space
by Geraldine Servant (CERN) In some classes of WIMP models, the Higgs boson could be copiously produced in association with a photon from dark matter annihilations in the center of our galaxy. The resulting photon spectrum possesses a line whose energy reflects the mass of the Higgs and of the WIMP and whose intensity depends on the WIMP spin and statistics. I will discuss how gamma-ray telescopes such as Fermi could provide information on the Higgs and dark matter complementary to that obtained at the LHC.
Challenges of Hadron Structure
by Paul Hoyer (Helsinki & CP³ Origins) Hadrons are bound states of quarks and gluons that can be classified as consisting of three quarks (baryons) or a quark and an antiquark (mesons). Their wave functions remain largely unknown even though the elementary quark and gluon interactions are governed by Quantum Chromodynamics (QCD). I discuss an approach to relativistic bound states based on an expansion in the Planck constant hbar. This allows the derivation of mesons and baryons at the Born level (excluding loop effects), and gives wave functions that have several intriguing properties.
Harmonic morphisms and bicomplex manifolds
by John Wood (Leeds) Harmonic morphisms are map which preserves Laplace’s equation; they can be characterized as harmonic maps which enjoy a partial conformality condition. We use functions of a bicomplex variable to give unified constructions of harmonic morphisms for different signatures. This uses the notion of complex-harmonic morphism between complex-Riemannian manifolds; we show how these are given by bicomplex-holomorphic functions on a bicomplex manifold when the codomain is one-bicomplex dimensional. On the way, we discuss some interesting conformal compactifications of complex-Riemannian manifolds by interpreting them as bicomplex manifolds such as the bicomplex quadric.
Resumming Leading Logarithmic Corrections in O(N)
by Lisa Carloni (Lund University) Abstract: I will explain how one can in principle calculate the leading logarithmic corrections to an observable at any order in the perturbative expansion from simple one-loop calculations. I will give an alternative proof for this. I will then describe the specific case of mπ and Fπ in O(N), and finally explain how we have been able to resum the series in the large N limit.
Center symmetry in the planar limit of SU(N) gauge theories with fermions in two-index representations, and orientifold planar equivalence
by Agostino Patella (Swansea) In gauge theories with some center symmetry, confinement and deconfinement are related to the realization of the center symmetry. I will discuss center symmetry in SU(N) gauge theories coupled to fermions in the two-index representations, and some peculiar properties of the large-N limit of these theories. With fermions in the (anti)symmetric representation, the theory is invariant at most under a Z2 center symmetry. This statement is true also in the large-N limit, but the symmetry group of the vacuum is enhanced to a U(1). I will review the Hamiltonian formalism for gauge theories, and the main ideas of the large-N limit and orientifold planar equivalence.
Self-Similarity and Power Asymptotics for Families of Stochastic Processes
by Bent Jørgensen (University of Southern Denmark) Abstract: We extend the notion of self-similarity to one-parameter families of stochastic processes, including Hougaard Lévy processes such as for example Brownian motion with drift, the Poisson process, the inverse Gaussian process, and the gamma compound Poisson process. Such families are characterized by having exponential family structure and power variance functions, and have many properties in common with conventional self-similar processes. We introduce a class of fractional Hougaard motions by means of a stochastic integral representation similar to the moving average representation of fractional Brownian motion. We show that such self-similar families appear as limits in a Lamperti-type limit theorem for families of stochastic processes. These results characterize a considerable class of self-similar families of stochastic processes with finite variance, in contrast to conventional self-similarity, where only fractional Brownian motion has finite variance. This is joint work with J. R. Martínez and C.G.B. Demétrio.

After the opening speeches by the Dean of the University of Southern Denmark, the Chair of the Danish National Research Foundation, and the presentation of the Centre by the Director, world renowned scientists will discuss the present and future of high energy physics. The scientific lectures will be short and at a beginning graduate studies level in physics. Besides marking the start of the new centre of excellence, the inauguration provides a unique opportunity to learn about our current understanding of the Universe and how we plan to get a step closer to unveiling some of its still unsolved mysteries such as the origin of bright and dark mass in the universe. The inauguration will be followed by an intense scientific program with a Workshop on the Origins of Mass problem on the 25th of November and a Winter School in Geometry and Theoretical Physics on the 26th and 27th of November.

Multi-Moment Maps
by Thomas Bruun Madsen (University of Southern Denmark) Abstract: One can think of torsion geometry as a triplet consisting of a smooth manifold endowed with a Riemannian metric and a three-form; the three-form is the torsion of a metric connection. If the three-form is closed, we have a strong geometry with torsion. The quest for systematic investigation of this type of geometry motivates the construction of a map, called a multi-moment map, which is very similar to the moment map from symplectic geometry. In my talk I will explain the theory of multi-moment maps.
Approaching QCD via Holography
by Francesco Nitti (APC, Paris) The concept of gauge/gravity is one of most promising tools in the search for a non-perturbative treatment of confing gauge theories in general, and QCD in particular. After a brief introduction to the original AdS/CFT conjecture for maximally supersymmetric Yang-Mills theory, I will give an overview of the bottom-up approach to the construction of a holographic dual for QCD. I will focus in particular on the ability of this approach of providing a realistic description of QCD thermodynamics, and of transport phenomena in the high-temperature deconfined phase.
The Mass Anomalous Dimension of SU(2) with two Adjoint Fermions
by Thomas Pickup (University of Oxford) Abstract: SU(2) with two Dirac fermions in the adjoint representation is an interesting candidate for a Walking Technicolor theory. Walking theories are required to be near conformal and have a large anomalous dimension. I will discuss Schrödinger Functional computations for measuring the running of the coupling as well as present the first measurement of the mass anomalous dimension.
Topology and the Universe
by Berian James (DARK, Copenhagen) In recent decades, astronomical observations have led to a broad, if incomplete, consensus description of the large-scale Universe: its evolution is determined by a handful of substances ('usual' matter like atoms, stars and galaxies; a hidden, but gravitationally attractive dark matter; the poorly understood and unfortunately named dark energy) all of which are changing under the influence of physical laws. In the region of the Universe visible to astronomers, great cosmological structures are observed---dense clusters in which the majority of galaxies form; vast and apparently empty voids; and a tangle of filaments that has been coined 'the cosmic web'. In this talk, I explore the role that topology, the mathematics of shape, plays in defining our understanding of the Universe. After reviewing the relationship between geometry and dynamics that characterises the modern Big Bang theory, I discuss three topics of broad scope: i) the classification of cosmological structures as a means of understanding both the physics of the very early Universe and the evolution and formation of galaxies; ii) the impact of some modern mathematical results from differential geometry that have yet to be fully assimilated into physics; and iii) the theory and measurements of the global topology of the Universe---does it extend infinitely in all directions, or wrap-around on itself, and how can we tell? Due to technical reasons the first few minutes of the talk are unfortunately missing from the recording.
QCD condensates in ADS/QCD
by Jacopo Bechi (CP3-Origins) Abstract: "In this talk I will focus on some issues about condensates and renormalization in AdS/QCD models. In particular I will consider the consistency of the AdS/QCD approach for scale dependent quantities as the chiral condensate questioned in some recent papers and the 4D meaning of the 5D cosmological constant in a model in which the QCD is dual to a 5D gravity theory. I will be able to give some arguments that the cosmological constant is related to the QCD gluon condensate".
