Next-to-leading-order QCD corrections to Higgs production in association with a jet

We compute the next-to-leading-order (NLO) QCD corrections to the Higgs pT distribution in Higgs production in association with a jet via gluon fusion at the LHC, with exact dependence on the mass of the quark circulating in the heavy-quark loops. The NLO corrections are presented including the topquark mass, and for the first time, the bottom-quark mass as well. Further, besides the on-shell mass scheme, we consider for the first time a running mass renormalisation scheme. The computation is based on amplitudes which are valid for arbitrary heavy-quark masses.& COPY; 2023 The Author(s). Published by Elsevier B.V.

Automated summary

We calculate the next-to-leading-order (NLO) QCD corrections to the Higgs pT distribution in Higgs production in association with a jet via gluon fusion at the LHC. The computation includes the exact dependence on the masses of the top and bottom quarks circulating in the heavy-quark loops, and considers both on-shell and running mass renormalisation schemes. The results are based on amplitudes that are valid for arbitrary heavy-quark masses.
