On the description of surface operators in N = 2* sym
Alday and Tachikawa [Lett. Math. Phys. 94, 87 (2010)] observed that the Nekrasov partition function of N = 2 SU(2) superconformal gauge theories in the presence of fundamental surface operators can be associated to conformal blocks of a 2D CFT with affine sl(2) symmetry. This can be interpreted as t...
