AdS3/CFT2 Correspondence and Space-Time N=3 Superconformal Algebra
Abstract
We study a Wess-Zumino-Witten model with target space AdS3 x (S3 x S3 x S1)/Z2. This allows us to construct space-time N=3 superconformal theories. By combining left-, and right-moving parts through a GSO and a Z2 projections, a new asymmetric (N,N)=(3,1) model is obtained. It has an extra gauge (affine) SU(2) symmetry in the target space of the type IIA string. An associated configuration is realized as slantwise intersecting M5-M2 branes with a Z2-fixed plane in the M-theory viewpoint.
