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

E. Bagnaschi, G. Degrassi, P. Slavich +1

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 t…
