Description:
Author(s): S. Abreu, F. Febres Cordero, H. Ita, M. Jaquier, B. Page, and M. Zeng We present the first numerical computation of two-loop amplitudes based on the unitarity method. As a proof of principle, we compute the four-gluon process in the leading-color approximation. We discuss the new method, analyze its numerical properties, and apply it to reconstruct the analytic form o... [Phys. Rev. Lett. 119, 142001] Published Thu Oct 05, 2017
