Новое о вычислении фейнмановских интегралов

Internal Reduction method for computing Feynman Integrals: https://arxiv.org/abs/1910.06275

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 H+2 jets production at the LHC, in both Euclidean and physical kinematical regions.
