N = 1 superconformal blocks with Ramond fields from AGT correspondence

Abstract

Abstract: We use AGT correspondence between N = 2 SUSY Yang-Mills theory on R4/Z2 and two-dimensional CFT model with the algebra Hsl (2)2 NSR to obtain the explicit expressions for 4-point NSR conformal blocks including Ramond fields in terms of Nekrasov partition functions and correlation functions of sl (2)2 WZW model. © 2013 SISSA, Trieste, Italy.
