"New Approaches for Two-Loop Multi-Leg Amplitudes"

Abstract:
The calculation of two-loop five-point scattering amplitudes has long been a bottleneck in obtaining NNLO predictions for many interesting LHC processes.
In the last few years, new approaches to the computation of such amplitudes have led to a proliferation of results in five-point massless scattering at two loops.
I will review these developments, and also discuss how they have been recently extended to compute the two-loop helicity amplitudes for the production of a heavy boson in association with two jets at the LHC.
