We will be discussing recent papers http://arxiv.org/abs/1309.0769, http://arxiv.org/abs/1309.1424
More detailed abstract: In this talk I will consider correlations of energy-, charge- and scalar-flow operators in four-dimensional N=4 Super Yang-Mills theory. These operators are constructed from the stress-energy tensor, R-currents, and scalar operators of the theory respectively and can physically be interpreted as detectors. Their correlations are related to weighted cross sections, which can be calculated perturbatively using amplitudes. In this talk I will describe a more efficient way to compute such correlations using superconformal symmetry, which is not only applicable in perturbation theory but can also be extended to the strong coupling regime.
