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…

Three-Loop Superfiniteness of N=8 Supergravity
Z. Bern, J. J. Carrasco, L. J. Dixon +3
We construct the three-loop four-point amplitude of N=8 supergravity using the unitarity method. The amplitude is ultraviolet finite in four dimensions. Novel cancellations, not pr…
