On the Lagrangian Realization of Non-Critical -Strings

arXiv:hep-th/9411221 · doi:10.1103/PhysRevD.51.6970

Abstract

A large class of non-critical string theories with extended worldsheet gauge symmetry are described by two coupled, gauged Wess-Zumino-Witten Models. We give a detailed analysis of the gauge invariant action and in particular the gauge fixing procedure and the resulting BRST symmetries. The results are applied to the example of strings.
