9. Exact results and Integrated correlator in 4d N=2 SCFTs

We consider the four-dimensional N=2 superconformal quiver gauge theory
arising from a Z2 orbifold of N=4 super Yang–Mills. Exploiting
supersymmetric localization, we analyze different types of integrated
correlators. In particular, we obtain exact expressions valid in the
large-N limit of the theory for integrated correlators involving two
Coulomb branch operators and two moment map...

10. Exact Three-Point Functions in N=2 Superconformal Field Theories

Dr G. Ferrando, G. Lefundes

We propose an integrability approach for planar three-point functions at finite coupling in N=2 superconformal field theories obtained as Z_K orbifolds of N=4 super Yang-Mills (SYM). Generalising the hexagon formalism for N=4 SYM, we reproduce the structure constants of Coulomb branch operators, previously obtained by supersymmetric localisation, as exact functions of the 't Hooft coupling....

12. Correlation Functions of Multiple Light-like Wilson Loops in N=4 SYM

Prof. J. Drummond

Scattering amplitudes are dual to polygonal light-like Wilson loops in planar N=4 super Yang-Mills theory. Here we will explore the computation of multiple light-like loops and demonstrate that many techniques familiar from the amplitude/single loop case extend to correlators of multiple loops, in particular one may use supertwistor Wilson loops, BCFW recursion and Q-bar equations to...
