Higgs production via gluon fusion in the POWHEG approach in the SM and
in the MSSM    [PDF]

E. Bagnaschi, G. Degrassi, P. Slavich, A. Vicini

We consider the gluon fusion production cross section of a scalar Higgs boson at NLO QCD in the SM and in the MSSM. We implement the calculation in the POWHEG approach, and match the NLO-QCD results with the PYTHIA and HERWIG QCD parton showers. We discuss a few representative scenarios in the SM and MSSM parameter spaces, with emphasis on the fermion and squark mass effects on the Higgs boson distributions.
