Some Exact Results in QCD-like and Chiral Gauge Theories

I present some exact non-perturbative results in QCD-like and chiral gauge theories. They are exact when supersymmetric gauge theories are perturbed by anomaly-mediated supersymmetry breaking (AMSB). Thanks to the UV-insensitivity of AMSB, SUSY results can be perturbed with no ambiguities even when applied to composite fields. I analytically derive chiral symmetry breaking in QCD-like theories. Our results for chiral gauge theories do not agree with what had been suggested by tumbling. We suggest alternative schemes of tumbling-like interpretations. We see no evidence that large SUSY breaking leads to phase transitions for the chiral symmetry breaking, perhaps protected by holomorphy.
