Gauge Dressing of 2D Field Theories
Ian I. Kogan, Alex Lewis, Oleg A. Soloviev
Abstract
By using the gauge Ward identities, we study correlation functions of gauged WZNW models. We show that the gauge dressing of the correlation functions can be taken into account as a solution of the Knizhnik-Zamolodchikov equation. Our method is analogous to the analysis of the gravitational dressing of 2D field theories.
