Title:
Loop operators in N=4 super-Yang-Mills, pure spinors and 2d gauge theory

Speaker:
Vasily Pestun

Abstract:
I will review the recent progress on the exact computation of expectation values and correlation functions in N=4 SYM involving 't Hooft and Wilson loops with certain supersymmetry. If the supersymmetry parameter is a pure spinor on a two-dimensional subspace S^2 of the space-time, then the correlation functions of certain Wilson loops on S^2 and certain 't Hooft loops, linked with the S^2, are computed by localization to a two-dimensional gauge theory on S^2, which is a semi-topological version of Yang-Mills-Hitchin theory.
