Parton-shower and fixed-order QCD effects in Higgs boson production in weak-boson fusion and its decays to bottom quarks
Abstract
We study the impact of higher-order QCD corrections on Higgs production via weak-boson fusion with subsequent decays of the Higgs boson to bottom-quark pairs. We consider realistic fiducial cuts and observe large corrections in a fixed-order calculation. They arise from the interplay of the particular fiducial cuts considered and the radiative corrections to the Higgs decay subprocess. Switching to a parton-shower-matched description of the decay captures a significant portion of the corrections already at the lowest order and improves the perturbative convergence of the calculation.
