Spontaneous supersymmetry breaking in two dimensional lattice super QCD
We report on a nonperturbative study of two dimensional N=(2,2) super QCD. Our lattice formulation retains a single exact supersymmetry at nonzero lattice spacing, and contains N _{f} fermions in the fundamental representation of a U(N _{c}) gauge group. The lattice action we employ contains an additional FayetIliopoulos term which is also invariant under the exact lattice supersymmetry. This work constitutes the first numerical study of this theory which serves as a toy model for understanding some of the issues that are expected to arise in four dimensional super QCD. As a result, we present evidence that the exact supersymmetry breaks spontaneously when N _{f} < N _{c} in agreement with theoretical expectations.
