Title: Parity symmetry breaking scale and Standard Model parameters

Room: 3024

Zoom: https://zoom.us/j/186024391

Host: Da Liu

Abstract : The strong CP problem can be solved by parity symmetry. We first review two classes of models: the ones with the minimal fermion content and the ones with the minimal Higgs content. We then focus on the latter class of models and show that the parity symmetry breaking scale is predicted to be the energy scale at which the standard model Higgs quartic coupling vanishes. Surprisingly, after fixing the parity symmetry breaking scale in this way, the gauge coupling constants unify at a high energy scale. We also discuss a model with a dark matter candidate and show that the dark matter direct detection rate is predicted as a function of the standard model parameters.

Title: Thoroughly AMSB QCD

Room: 3024

Host: John Terning

Abstract: Recently it has been demonstrated that anomaly-mediated supersymmetry breaking (AMSB) is a valuable tool for understanding the low-energy phases of non-SUSY gauge theories. For example, applying AMSB to SUSY SU(N) gauge theories with quarks in the fundamental leads to scalar potentials with chiral symmetry breaking minima. Furthermore, the application of AMSB to a class of SUSY SO(N) gauge theories gave the first analytic demonstration of confinement, via the dual Meissner effect, and continuous chiral symmetry breaking in a non-SUSY gauge theory. In this talk I will review these developments and then begin an exploration of the rich moduli space structure of AMSB-deformed SU(N) gauge theories. In particular, we find that these theories often possess "hidden" runaways, closely related to the usual baryonic runaways. Being stabilized around Lambda_QCD, these should not be interpreted as problems with the theory. Rather, they simply signal that the non-SUSY chiral symmetry breaking global minimum is only a local minimum in the SUSY limit. Understanding these runaways is crucial if we want to use AMSB to generate phenomenological models of QCD.
