Conformal blocks of Wess-Zumino-Witten model from its free-field representation

A bstract A powerful approach to the celebrated Wess-Zumino-Witten (WZW) model is provided by its free-field realization. However, explicit calculations of conformal blocks are not described in the literature in full detail. We begin this study with the simplest cases of the $$ \...
