KINKS INSIDE SUPERSYMMETRIC DOMAIN RIBBONS

We study a variety of supersymmetric systems describing sixth-order in teractions between two coupled real superfields in 2+1 dimensions. We search for BPS domain ribbon solutions describing minimum energy stati c field configurations that break one half of the supersymmetries. We then use the supersymmetric system to investigate the behavior of meso ns and fermions in the background of the defects. In particular, we sh ow that certain BPS domain ribbons admit internal structure in the for m of bosonic kinks and fermionic condensate, for a given range of the two parameters that completely identify the class of systems.
