Rationalisation of multiple square roots in Feynman integrals
Georgios Papathanasiou, Stefan Weinzierl, Konglong Wu +1
Feynman integrals are very often computed from their differential equations. It is not uncommon that the -factorised differential equation contains only dlog-forms wit…
Full-colour double-virtual amplitudes for associated production of a Higgs boson with a bottom-quark pair at the LHC
Simon Badger, Heribertus Bayu Hartanto, Rene Poncelet +3
We present the double-virtual amplitudes contributing to the production of a Higgs boson in association with a pair at the Large Hadron Collider. We perform the computat…
Two-loop amplitudes for corrections to production at the LHC
Simon Badger, Heribertus Bayu Hartanto, Zihao Wu +2
We present the two-loop helicity amplitudes contributing to the next-to-next-to-leading order QCD predictions for W-boson production in association with two photons at the Large Ha…
A new method for finding more symmetry relations of Feynman integrals
Zihao Wu, Yang Zhang
We introduce a new method for deriving Feynman integral symmetry relations. By solving the ansatz of momentum transformation in the field of rational functions rather than constant…
