Description

Scattering amplitudes have always been essential to compute cross sections and production rates at colliders. In the last few years, though, there has been terrific progress in understanding the rich mathematical structure of scattering amplitudes, the more so in specific kinematic regions, like the Regge limit. In this talk, I will outline what we have learnt about the weak-coupling expansions of amplitudes in quantum field theories, and then specify it to the Regge limit of QCD and of N=4 super-Yang-Mills theory.
