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

Understand

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.
