Progress on Ultraviolet Finiteness of Supergravity
Z. Bern, J. J. M. Carrasco, H. Johansson
In this lecture we summarize recent calculations pointing to the possible ultraviolet finiteness of N = 8 supergravity in four dimensions. We outline the modern unitarity method, w…

Maximally Supersymmetric Planar Yang-Mills Amplitudes at Five Loops
Z. Bern, J. J. M. Carrasco, H. Johansson +1
We present an ansatz for the planar five-loop four-point amplitude in maximally supersymmetric Yang-Mills theory in terms of loop integrals. This ansatz exploits the recently obser…
