Next-to-next-to-next-to-leading order QCD corrections to photon-pair production
Michal Czakon, Felix Eschment, Terry Generet +1
The production of two isolated photons in high-energy hadron collisions poses a challenge to perturbative QCD because of large corrections through next-to-next-to-leading order (NN…

Subleading Effects in Soft-Gluon Emission at One-Loop in Massive QCD
Michał Czakon, Kilian Erhard Minguez, Felix Eschment
We provide the last missing ingredient necessary to approximate one-loop amplitudes in QCD with massive quarks in the limit of vanishing energy of a single gluon up to terms suppre…

Quark Mass Effects in Higgs Production
Michał Czakon, Felix Eschment, Marco Niggetiedt +2
We examine the effect of finite top- and bottom-quark masses on the Higgs production cross section in the gluon-gluon fusion channel. We employ both and on-s…
