(05.02.) Double Correlations in N=4 Theories

In this talk I will consider double-correlations of energy-, charge- and scalar-flow operators in four-dimensional theories with N=4 superconformal symmetry. These flow operators are constructed from components of the energy-momentum supermultiplet and can physically be interpreted as detectors. I will describe a way to compute their double-correlations that efficiently uses the superconformal symmetry. A crucial step in this method is to find an expression for the four-point correlation function of the energy-momentum multiplet as a particular invariant of a subalgebra of the theory, which I will construct explicitly.
