Abstract

We determine the vacuum structure and phases of N = 1 theories obtained via a mass μ for the adjoint chiral superfield in N = 2, SO(nc) SQCD. For large number of flavors these theories have two groups of vacua. The first exhibits dynamical breaking of flavor symmetry USp(2nf) → U(nf) and arises as a...
