Gauged Heterotic Sigma-Models

Abstract

The gauging of isometries in general sigma-models which include fermionic terms which represent the interaction of strings with background Yang-Mills fields is considered. Gauging is possible only if certain obstructions are absent. The quantum gauge anomaly is discussed, and the (1,0) supersymmetric generalisation of the gauged action given.Comment: 10 pages, phyzzx, QMW-93-25 (Blank lines created by mailer removed, so this version should be TeXable
