Abstract

A path integral formulation of G/H conformal theories is presented, based on gauged Wess-Zumino-Witten actions. The conformal charge of the model is c=cG-cH, exactly as in the GKO construction. Ghost modes appear in the formalism as a result of gauge fixing. As a consequence, the holomorphic stress-tensor T(z) obtained in our construction has ghost contributions. We find T(z)=TG-TH only for matrix elements of physical states which are also ghost free.
