Title: Strong-coupling results in N=2 superconformal gauge theories

Abstract: In this talk I will discuss recent developments in the study of different kinds of correlators in four-dimensional N = 2 superconformal gauge theories. Using supersymmetric localization, it is possible to map the computation of these correlation functions, i.e. 3-point functions of chiral primary operators and correlators of n coincident twisted Wilson loops, to an interacting matrix model and obtain expressions that are valid for any value of the ’t Hooft coupling in the planar limit of the theory. In particular, I will focus on the strong-coupling regime, where these expressions allow us to compute the leading and, sometimes, subleading orders of the correlators in an analytic way.
