dias September 16, 2013 New Physics from vector-like Technicolor: new opportunities for astrophysics and collider phenomenology by Roman Pasechnik (Lund University) I will discuss a new microscopic model for high-scale strongly-coupled dynamics in its simplest possible formulation based upon a single vector-like $SU(2)_{\rm W}$ T-quark doublet (with hypercharge $Y_Q=0$) confined under the minimal $SU(2)_{\rm TC}$ (in principle, any even) T-color group. Besides it naturally avoids stringent EW constraints at the fundamental level and may explain possible (small) deviations in Higgs couplings, it provides dynamical EW symmetry breaking via an effective Higgs mechanism. I will outline interesting theoretical and phenomenological opportunities related with lightest physical T-pion, T-sigma and T-baryon states in the considering scenario. In particular, I will illustrate why an odd QCD-like $SU(2n+1)_{TC}$ group of confinement has been excluded by XENON100 data on spin-independent Dark Matter cross section if the T-baryon number is conserved. Scalar T-baryon Dark Matter in the simplest even $SU(2)_{TC}$ group offers a prominent way out and distinctive collider signatures. Possible ways to construct the composite Higgs doublets in the vector-like Technicolor will be discussed. Finally, extra hybrid (bi-fundamental) color-T-color representations give rise to partial neutrino compositeness and effective see-saw mechanism for small neutrino mass generation in a natural way.
dias November 2, 2010 at 16:00 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. Public Lecture Prof. 't Hooft gives a lecture on Black Holes in Elementary Physics. The lecture is intended for the general public. Everybody is welcome to attend.

dias October 26, 2009 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.
