On structure constants and fusion rules in the $SL(2,\BC)/SU(2)$ WZNW model

Abstract

A closed formula for the structure constants in the SL(2,C)/SU(2) WZNW model is derived by a method previously used in Liouville theory. With the help of a reflection amplitude that follows from the structure constants one obtains a proposal for the fusion rules from canonical quantization. Taken together these pieces of information allow an unambigous definition of any genus zero n-point function.

25 pages, AMSLATEX2e, discussion of canonical quantization and fusion rules clarified, a few corrections
