Abstract

In N=1 super Yang-Mills theory in three spacetime dimensions, with a simple gauge group and a Chern-Simons interaction of level , the supersymmetric index $\Tr (-1)^F$ can be computed by making a relation to a pure Chern-Simons theory or microscopically by an explicit Born-Oppenheimer calculation on a two-torus. The result shows that supersymmetry is unbroken if (with the dual Coxeter number of ) and suggests that dynamical supersymmetry breaking occurs for . The theories with large are massive gauge theories whose universality class is not fully described by the standard criteria.
