Integrand Analysis, Leading Singularities and Canonical Bases beyond Polylogarithms
Felix Forner, Cesare Carlo Mella, Christoph Nega +2
In this paper, we elaborate on the connection between leading singularities and canonical bases of Feynman integrals beyond polylogarithms. We start by discussing a notion of leadi…

Two-Loop Master Integrals for Mixed QCD-EW Corrections to Through
Robin Marzucca, Andrew J. McLeod, Christoph Nega
We consider mixed strong-electroweak corrections to Higgs production via gluon fusion, in which the Higgs boson couples to the top quark. Using the method of differential equations…

On the photon self-energy to three loops in QED
Felix Forner, Christoph Nega, Lorenzo Tancredi
We compute the photon self-energy to three loops in Quantum Electrodynamics. The method of differential equations for Feynman integrals and a complete -factorization of the form…
