Twisted sl(3, C)(2)k Current Algebra: Free Field Representation and Screening Currents
Xiang-Mao Ding, Mark D. Gould, Yao-Zhong Zhang
Abstract
Motivated by applications of twisted current algebras in description of the entropy of Ads3 black hole, we investigate the simplest twisted current algebra sl(3, C)(2)k. Free field representation of the twisted algebra and the corresponding twisted Sugawara energy-momentum tensor are obtained by using three (β,γ) pairs and two scalar fields. Primary fields and two screening currents of the first kind are presented.
