Title: “Exact results for the simplest four-point function in N=4 SYM”

Abstract: In the last two decades integrability has found an unexpected application to describe the planar limit of conformal, higher dimensional gauge theories. The most outstanding example is that of the supersymmetric N = 4 gauge theory in four dimensions, known to be dual to string theory on AdS5*S5 background. In this talk, I will explain how the computation of a particularly simple example of the correlation function of four gauge-invariant operators can be done by using a geometrical decomposition in terms of non-local form factors.
