| Summary: | 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

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
