摘要：

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. © 1990.
