BPS domain walls in super Yang-Mills and Landau-Ginzburg models

BPS domain walls in super Yang-Mills and Landau-Ginzburg models
BPS domain walls in super Yang-Mills and Landau-Ginzburg models
We study domain walls in two different extensions of super Yang-Mills characterized by the absence of a logarithmic term in their effective superpotential. The models, defined by the usual gaugino condensate and an extra field Y, give different patterns of domain walls despite both leading to the same effective limit for heavy Y, i.e. the Veneziano-Yankielowicz effective lagrangian of super Yang-Mills. We explain the origin of those differences and also give a physical motivation for introducing the field Y.

Abstract

We study domain walls in two different extensions of super Yang-Mills characterized by the absence of a logarithmic term in their effective superpotential. The models, defined by the usual gaugino condensate and an extra field Y, give different patterns of domain walls despite both leading to the same effective limit for heavy Y, i.e. the Veneziano-Yankielowicz effective lagrangian of super Yang-Mills. We explain the origin of those differences and also give a physical motivation for introducing the field Y.
