N = (0, 2) Heterotic Sigma Models: Geometric Structure, Holomorphic Anomaly and Exact Beta Functions
Xiaoyi Cui
(MPI, Bonn)
Abstract:
We study geometric aspects and holomorphic properties of N = (0, 2) Heterotic Sigma Models over symmetric spaces, and derive a number of exact relations for the β functions in terms of the analogy to the NSVZ β function in four-dimensional Yang-Mills. We will show that in spite of the heterotic nature, the isometries are preserved at the quantum level. We will also discuss the N = (0, 2) supercurrent multiplet (the so-called hypercurrent) and its anomalies, as well as the “Konishi anomaly.” This gives us another method for finding two-loop β functions. The talk is based on joint work with J. Chen, M. Shifman and A. Vainshtein.
