N=(0,2) Deformation of CP(1) Model: Two-dimensional Analog of N=1 Yang-Mills Theory in Four Dimensions
Xiaoyi Cui, M. Shifman
We consider two-dimensional sigma models with the CP(1) target space. A minimal model of this type has one left-handed fermion. Nonminimal extensions contain, i…

N=(0,2) Supersymmetry and a Nonrenormalization Theorem
Xiaoyi Cui, M. Shifman
In this paper we continue the study of perturbative renormalizations in an supersymmetric model. Previously we analyzed one-loop graphs in the heterotically def…
