Maths HEP Lunchtime Seminars: Exact correlation functions in 4d N = 2 SCFTs
18 March 2016 13:00 in CM221
We describe correlation functions of chiral primary operators in N=2 superconformal field theories, and show that they can be determined exactly using techniques from localization and the tt* equations. We provide the complete solution for 2- and 3-point functions of chiral primaries in N=2 SU(2) superconformal QCD and we compare the results to a 2-loop perturbative computation. We also comment on extensions to more general setups and implications for generic N=2 SCFTs.
