TL;DR
This paper investigates the conditions under which isometries can be gauged in fermionic sigma-models, addressing obstructions, quantum anomalies, and supersymmetric extensions relevant for string-background interactions.
Contribution
It provides a detailed analysis of gauging obstructions, discusses quantum gauge anomalies, and introduces a (1,0) supersymmetric generalisation of the gauged sigma-model action.
Findings
Gauging isometries requires absence of certain obstructions.
Quantum gauge anomalies are analyzed and discussed.
A (1,0) supersymmetric extension of the gauged action is formulated.
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.
