Analytic two-loop amplitudes for di-jet and $γ +$ jet production mediated by a heavy-quark loop

Federico Coro, Christoph Nega, Lorenzo Tancredi +1

In this paper, we present analytical results for the two-loop QCD corrections to the production of two partons or a photon and a parton in hadronic collisions, mediated by loops of…

Analytic two-loop amplitudes for $q q ˉ \to γ γ$ and $g g \to γ γ$ mediated by a heavy-quark loop

Matteo Becchetti, Federico Coro, Christoph Nega +2

We address the analytic computation of the two-loop scattering amplitudes for the production of two photons in parton-parton scattering, mediated by loops of heavy quarks. Due to t…

Two-Loop Master Integrals for Mixed QCD-EW Corrections to $g g \to H$ Through $O (ε^{2})$

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…
