Space-Time S-matrix and Flux-Tube S-matrix in Planar N=4 SYM Theory

Description
In planar N=4 Super-Yang-Mills theory there is a map between gluons scattering amplitudes and null polygonal Wilson loops. This remarkable
duality allows one to make an important step forward by Operator-Product-Expanding the scattering amplitudes.  This action breaks down the four-dimensional amplitudes into a sequence of two-dimensional processes taking place on the flux tube sourced by the dual Wilson loops. In this talk I will explain how the integrable structures of the flux tube theory can be used for computing scattering amplitudes in this theory at any value of the coupling.
