Renormalization of the pseudoscalar operator at four loops in QCD
Long Chen, Michał Czakon, Marco Niggetiedt
We present the renormalization constant of the pseudoscalar operator defined with a non-anticommuting in dimensional regularization up to four-loop order in perturbative Quan…

Open -hadron production at hadron colliders in QCD at next-to-next-to-leading-order and next-to-next-to-leading-logarithmic accuracy
Michał Czakon, Terry Generet, Alexander Mitov +1
We report on a calculation of open heavy-flavor production at hadron colliders which extends to next-to-next-to-leading order (NNLO) accuracy the classic NLO-accurate formalism dev…

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…
