Abstract

Author(s): S. Abreu, F. Febres Cordero, H. Ita, B. Page, and M. Zeng We present a calculation of the planar two-loop five-gluon amplitudes. The amplitudes are obtained in a variant of the generalized unitarity approach suitable for numerical computations, which we extend for use with finite field arithmetics. Employing a new method for the generation of unitarity-com... [Phys. Rev. D 97, 116014] Published Wed Jun 20, 2018
