Manifest Ultraviolet Behavior for the Three-Loop Four-Point Amplitude of N=8 Supergravity
Z. Bern, J. J. M. Carrasco, L. J. Dixon +2
Using the method of maximal cuts, we obtain a form of the three-loop four-point scattering amplitude of N=8 supergravity in which all ultraviolet cancellations are made manifest. T…

New Relations for Gauge-Theory Amplitudes
Z. Bern, J. J. M. Carrasco, H. Johansson
We present an identity satisfied by the kinematic factors of diagrams describing the tree amplitudes of massless gauge theories. This identity is a kinematic analog of the Jacobi i…
