Logarithmic Currents in the SU(2)_0 WZNW model
arXiv:hep-th/0102156 · doi:10.1016/S0370-2693(01)00965-0
Abstract
We study four point correlation functions of the spin 1 operators in the SU(2)_0 WZNW model. The general solution which is everywhere single-valued has logarithmic terms and thus has a natural interpretation in terms of logarithmic conformal field theory. These are not invariant under all the crossing symmetries but can remain if fields possess additional quantum numbers.
