Two-Dimensional Models With (0,2) Supersymmetry: Perturbative Aspects

High Energy Physics - Theory 2007-05-23 v3

Abstract

Certain perturbative aspects of two-dimensional sigma models with (0,2) supersymmetry are investigated. The main goal is to understand in physical terms how the mathematical theory of ``chiral differential operators'' is related to sigma models. In the process, we obtain, for example, an understanding of the one-loop beta function in terms of holomorphic data. A companion paper will study nonperturbative behavior of these theories.
