HPro: A NLO Monte-Carlo for Higgs production via gluon fusion with finite heavy quark masses

Understand

We compute fully differential next-to-leading order QCD cross-sections for Higgs boson production via gluon fusion in the Standard Model.

• We maintain the full dependence of the cross-sections on the top and bottom quark mass.
• We find that finite quark mass effects are important given the achieved precision of QCD predictions for gluon fusion.
• Our Monte-Carlo program, HPro, can correct existing NNLO fully differential calculations, which employ the approximation of an infinitely heavy top and a vanishing bottom quark Yukawa coupling, for heavy quark finite mass effects through NLO.
