BPS Domain Walls in Supersymmetric QCD: Higher Unitary Groups
Abstract
We consider the N=1 supersymmetric QCD with SU(N_c) gauge group involving N_f = N_c - 1 pairs of chiral matter multiplets in fundamental and antifundamental color representations. For this theory in the framework of the effective lagrangian approach, we solve the BPS equations for the domain walls interpolating between different vacua. The equations always have a unique solution for the walls interpolating between the chirally symmetric and a chirally asymmetric vacua. For the walls interpolating between different chirally asymmetric vacua, the equations admit two different solutions which exist when the mass of the matter field is below some critical value m*. At m = m*, two branches join together and, at m > m*, no BPS - saturated complex domain walls exist.
