The superconformal index of (2,0) theory with defects

Abstract
String theory predicts the existence of a class of interacting superconformal field theories in six dimensions which arise on the world-volume of coincident M5 branes. There are important non-local operators in these theories corresponding to intersecting M2 and M5 branes. I will explain how to compute the superconformal index in the presence of such operators using five-dimensional supersymmetric gauge theory. The answers are in 1-1 correspondence with characters of representations of a class of `chiral algebras’. I will discuss potential applications of this result for bootstrapping correlation functions.
