Abstract
We study the spectrum of the domain walls interpolating between different chirally asymmetric vacua in supersymmetric QCD with the SU (3) gauge group and including 2 pairs of chiral matter multiplets in fundamental and anti-fundamental representations. For small enough masses m<m ∗ ≈.286Λ SQCD , there are two different domain wall solutions which are BPS-saturated and two types of “wallsome sphalerons”. At m=m ∗ , two BPS branches join together and, in the interval m ∗ <m<m ∗∗ ≈3.704Λ SQCD , BPS equations have no solutions but there are solutions to the equations of motion describing a non-BPS domain wall and a sphaleron. For m>m ∗∗ , there are no solutions whatsoever.
