Multi-loop Integrand Reduction with Computational Algebraic Geometry
Simon Badger, Hjalte Frellesvig, Yang Zhang
We discuss recent progress in multi-loop integrand reduction methods. Motivated by the possibility of an automated construction of multi-loop amplitudes via generalized unitarity c…

A Two-Loop Five-Gluon Helicity Amplitude in QCD
Simon Badger, Hjalte Frellesvig, Yang Zhang
We compute the planar part of the two-loop five gluon amplitude with all helicities positive. To perform the calculation we develop a D-dimensional generalized unitarity procedure…
