Title:
Space-time S-matrix and Flux-tube S-matrix: Part I
Speaker:
Abstract:
In planar N=4 Super-Yang-Mills theory there exists a map between gluon 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 these two talks, we shall explain how the integrable structures of the flux tube theory can be used for computing scattering amplitudes at any value of the coupling constant.
