Scalar product of current blocks in WZW theory

We compute by free field techniques the scalar product of the genus-zero current blocks for the WZW theory with general compact Lie group. The result is given by integral expressions closely related to integral representations of the solutions of the Knizhnik-Zamalodchikov equations studied recently...

Summary:We compute by free field techniques the scalar product of the genus-zero current blocks for the WZW theory with general compact Lie group. The result is given by integral expressions closely related to integral representations of the solutions of the Knizhnik-Zamalodchikov equations studied recently by Schechtman and Varchenko, and Matsuo.
