Internal Reduction method for computing Feynman Integrals
arXiv:1910.06275 · doi:10.1007/JHEP02(2020)112
Abstract
A new approach to compute Feynman Integrals is presented. It relies on an integral representation of a given Feynman Integral in terms of simpler ones. Using this approach, we present, for the first time, results for a certain family of non-planar five-point two-loop Master Integrals with one external off-shell particle, relevant for instance for jets production at the LHC, in both Euclidean and physical kinematical regions.
