Large-N Solution of the Heterotic N=(0,1) Two-Dimensional O(N) Sigma Model

preprint2010arXivOpen access

Abstract

In this paper we build a family of heterotic deformations of the O(N) sigma model. These deformations break (1,1) supersymmetry down to (0,1) symmetry. We solve this model at large N. We also find an alternative superfield formulation of the heterotic CP^N sigma model which was discussed in the literature before.
