Abstract

Gauge theories can be solved exactly slightly away from the supersymmetric (SUSY) limit softly broken by anomaly mediation when the size of SUSY breaking is much smaller than the dynamical scale (m≪Λ). We show empirical evidence that the near-SUSY limit is continuously connected to the non-SUSY limit (m≫Λ) in SU(Nc) gauge theories with Nf quarks in the fundamental representation. The evidence includes the behavior of quark bilinear condensate and gluon condensates, light hadron spectra, and consistency with the large Nc limit including the Witten-Veneziano relations between the topological susceptibility and mη′ and mπ. In addition, we present new predictions when Nf/Nc≳O(1).
