Coupling Nonlinear σ-Models to Relaxed Yang-Mills Supermultiplets in (2,0)-Superspace

Abstract

Following a previous work on 2-dimensional Abelian (2,0)-gauge theories, one reacesses the analysis of the consistency of the dynamics of (2,0) "relaxed" Yang-Mills super-potentials and their coupling to (2,0)-nonlinear σ-model, by gauging the isotropy or the isometry group of the latter. One pays special attention to the extra "chiral-like" component-field gauge potential that comes out from the relaxation of superspace constraints.
