摘要：

Current-current deformations for WZW models of semi-simple compact groups are discussed in a sigma model approach. We start with the Abelian rank one group U(I). Afterwards, we keep the rank one but allow for non-Abelian structures by considering SU(2). Finally, we present the general case of rank larger than one.
