High Energy Theory Seminar - IAS - Pedro Vieira, Perimeter Institute - Space-Time S-matrix and Flux-Tube S-matrix
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. The integrable structures of the flux tube theory can be used for computing scattering amplitudes this way regardless of the value of the coupling by breaking the polygons into smaller building blocks, the Pentagon transitions.
