Title:
Thoroughly AMSB QCD

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 many of the “runaways” often present in SUSY-broken gauge theories are prevented by AMSB. This provides strong evidence that the chiral symmetry breaking minima in the small SUSY-breaking limit are continuously connected those of non-SUSY (real-world) QCD.
