The superconformal index of class S theories of type D

Abstract

We consider the superconformal index of class S theories of type D, which arise by compactification of the (2, 0) D n theories on a punctured Riemann surface C. We also allow for the presence of twist lines on C associated to the ℤ2 outer automorphism of D n . For the two-parameter slice (p = 0, q, t) in the space of superconformal fugacities, we determine the 2d TQFT that computes the index. © 2014 The Author(s).
