N=(0, 2) Deformation of (2, 2) Sigma Models: Geometric Structure, Holomorphic Anomaly and Exact Beta Functions
Jin Chen, Xiaoyi Cui, Mikhail Shifman +1
We study N=(0,2) deformed (2,2) two-dimensional sigma models. Such heterotic models were discovered previously on the world sheet of non-Abelian strings supported by certain four-d…

Perturbative Aspects of Heterotically Deformed CP(N-1) Sigma Model. I
Xiaoyi Cui, M. Shifman
In this paper we begin the study of renormalizations in the heterotically deformed N=(0,2) CP(N-1) sigma models. In addition to the coupling constant g^2 of the undeformed N=(2,2)…
