Prelogarithmic operators and Jordan blocks in SL(2)_k affine algebra

High Energy Physics - Theory 2009-11-07 v3

Abstract

The free field description of logarithmic and prelogarithmic operators in non compact Wess-Zumino-Witten model is analysed. We study the structure of the Jordan blocks of the SL(2)_k affine algebra and the role of the puncture operator in the theory in relation with the unitarity bound.
