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

Following a previous work on Abelian (2,0)-gauge theories, one reassesses here the task of coupling (2,0) relaxed Yang-Mills superpotentials to a (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.

A Remark on the Geometry of Two-Dimensional Anisotropic Non-Linear Sigma-Models

One discusses here the connection between σ-model gauge anomalies and the existence of a connection with torsion that does not flatten the Ricci tensor of the target manifold, by considering a number of non-symmetric coset spaces. The influence of an eventual anisotropy on a certain direction of the target manifold is also contemplated.

(2,0)-Super-Yang-Mills Coupled to Non-Linear Sigma-Model

Considering a class of (2,0)-super-Yang-Mills multiplets that accommodate a pair of independent gauge potentials in connection with a single symmetry group, we present here their coupling to ordinary matter and to non-linear $σ$-models in (2,0)-superspace. The dynamics and the couplings of the gauge potentials are discussed and the interesting feature that comes out is a sort of ``chirality'' for one of the gauge potentials once light-cone coordinates are chosen.
