Where: The CP³ meeting room
Friday this week, we celebrate the first two Master degrees obtained at CP3-Origins.
Matin Mojaza defended his master thesis on Aspects of Conformal Gauge Theories May this year: Strong dynamics of asymptotically free gauge theories is an unsolved problem. For large number of flavors we believe the dynamics to be controlled by an infrared stable fixed point.
A key feature, still remaining to be understood, is the non-perturbative dynamics driving theories with a lower number of flavors away from the perturbative fixed point. In this presentation of my thesis I briefly present this issue and will in particular discuss the phases of gauge theories. I present a new investigation of the finite temperature structure of asymptotically free gauge theories possessing a perturbative infrared stable fixed point based on the free energy density at the fixed point. The analysis has been done for different gauge groups and different matter content, in particular both vectorlike and chiral gauge theories.
As another aspect of gauge theories flowing to an infrared fixed point I will discuss the possibility of having gauge-gauge duality at the fixed point in the sense of Universality observed in condensed matter physics. In particular I present a novel non-supersymmetric gauge-gauge duality. Remarkably, this proposal constitutes the first non-supersymmetric duality valid for any number of colors and it predicts the upper bound of the anomalous dimension of the fermion mass at the fixed point to be γ* ≤ 1.
Phongpichit Channuie defended his master thesis on Conformal Dynamics in 4D and Applications to LHC and Cosmology May last year. His thesis discusses the mechanism of dynamical electroweak symmetry breaking (DESB) termed Technicolor (TC) and supersymmetric gauge theories (SUSY). After introducing TC and SUSY, the thesis subsequently aims to tie such two agenda. The resulting model is named a supersymmetric technicolor model.
Mojaza and Channuie were both advised by Francesco Sannino and are both continuing their studies at CP3-Origins as Ph.D. students.
