Four point functions in the SL (2, R) WZW model
We consider winding conserving four point functions in the SL (2, R) WZW model for states in arbitrary spectral flow sectors. We compute the leading order contribution to the expansion of the amplitudes in powers of the cross ratio of the four points on the worldsheet, both in the m- and x-basis, wi...
