Abstract:
We study dynamics of two-dimensional non-abelian gauge theories with $$ \mathcal{N} $$ N = (0 , 2) supersymmetry that include $$ \mathcal{N} $$ N = (0 , 2) supersymmetric QCD and its generaliza- tions. In particular, we present the phase diagram of $$ \mathcal{N} $$ N = (0 , 2) SQCD and determine its massive and low-energy spectrum. We find that the theory has no mass gap, a nearly constant distribution of massive states, and lots of massless states that in general flow to an interacting CFT. For a range of parameters where supersymmetry is not dynamically broken at low energies, we give a complete description of the low-energy physics in terms of 2d $$ \mathcal{N} $$ N = (0 , 2) SCFTs using anomaly matching and modular invariance. Our construction provides a vast landscape of new $$ \mathcal{N} $$ N = (0 , 2) SCFTs which, for small values of the central charge, could be used for building novel heterotic models with no moduli and, for large values of the central charge, could be dual to AdS 3 string vacua.
