Seminar Room 2 (DESY, building 2a)

The talk will focus on the properties of extremal correlation functions in the N=2 chiral ring of four-dimensional N=2 superconformal field theories with non-trivial superconformal manifolds. I will describe a programme based on a combination of localization and tt* techniques that aims to uncover the exact analytic form of such correlation functions. Special emphasis will be given to the case of SU(N) superconformal QCD theories where a new solution of the tt* equations is proposed with surprising consequences.
