BRST quantization of the gauged WZW action and coset conformal field theories
Description
The relation of the gauged Wess-Zumino-Witten models describing G/H conformal field theories and the GKO construction is investigated in the BRST framework. A nilpotent operator Q is constructed and the physical spectrum and unitarity of the theory is analyzed. When H is the Cartan subalgebra of G the BRST invariant current operators (the physical currents) are shown to be the parafermionic operators. (orig.)
