We study the worldvolume dynamics of 1/2-supersymmetric domain walls in N = 1 supersymmetric QCD with Nf = N flavors, and exhibit an enhancement of supersymmetry for the reduced moduli space associated with broken flavor symmetries. We provide an explicit construction of the worldvolume superalgebra which corresponds to an N = 2 Kähler sigma model in 2 + 1D deformed by a potential, given by the norm squared of a U(1) Killing vector, resulting from the flavor symmetries broken by unequal quark masses. This framework leads to a worldvolume description of novel two-wall-junction configurations, which are 1/4-supersymmetric objects, but nonetheless preserve two supercharges when viewed as kinks on the wall worldvolume.
