Constructing d-log integrands and computing master integrals for three-loop four-particle scattering
Johannes Henn, Bernhard Mistlberger, Vladimir A. Smirnov +1
We compute all master integrals for massless three-loop four-particle scattering amplitudes required for processes like di-jet or di-photon production at the LHC. We present our re…
RationalizeRoots: Software Package for the Rationalization of Square Roots
Marco Besier, Pascal Wasser, Stefan Weinzierl
The computation of Feynman integrals often involves square roots. One way to obtain a solution in terms of multiple polylogarithms is to rationalize these square roots by a suitabl…
Integration-by-parts reductions of Feynman integrals using Singular and GPI-Space
Dominik Bendle, Janko Boehm, Wolfram Decker +5
We introduce an algebro-geometrically motived integration-by-parts (IBP) reduction method for multi-loop and multi-scale Feynman integrals, using a framework for massively parallel…
Analytic form of the full two-loop five-gluon all-plus helicity amplitude
S. Badger, D. Chicherin, T. Gehrmann +6
We compute the full-color two-loop five-gluon amplitude for the all-plus helicity configuration. In order to achieve this, we calculate the required master integrals for all permut…
The two-loop five-particle amplitude in supergravity
D. Chicherin, T. Gehrmann, J. M. Henn +3
We compute for the first time the two-loop five-particle amplitude in supergravity. Starting from the known integrand, we perform an integration-by-parts reduction…
Matter dependence of the four-loop cusp anomalous dimension
Johannes M. Henn, Tiziano Peraro, Maximilian Stahlhofen +1
We compute analytically the matter-dependent contributions to the quartic Casimir term of the four-loop light-like cusp anomalous dimension in QCD, with fermion and sca…
