Anomalies of Minimal N=(0, 1) and N=(0, 2) Sigma Models on Homogeneous Spaces
Jin Chen, Xiaoyi Cui, Mikhail Shifman +1
We study chiral anomalies in and two-dimensional minimal sigma models defined on generic homogeneous spaces . Such minimal theories contain only (…
On Isometry Anomalies in Minimal N=(0,1) and N=(0,2) Sigma Models
Jin Chen, Xiaoyi Cui, Mikhail Shifman +1
The two-dimensional minimal supersymmetric sigma models with homogeneous target spaces and chiral fermions of the same chirality are revisited. We demonstrate that the Moore-…
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…
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…
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)…
