We present a next-to-leading order calculation of Higgs boson production via gluon fusion interfaced to shower Monte Carlo programs, implemented according to the POWHEG method. A detailed comparison with MC@NLO and PYTHIA is carried out for several observables, for the Tevatron and LHC colliders. Comparisons with next-to-next-to-leading order results and with resummed ones are also presented.

NLO single-top production matched with shower in POWHEG: s- and t-channel contributions (2009, methodology): “In previous works [25, 26, 29, 32], we have extensively discussed the presence of sizable mismatches between POWHEG and MC@NLO results in the rapidity difference between the hardest jet and the heavy system recoiling against it.”
Higgs production with a central jet veto at NNLL+NNLO (2010, methodology): “Currently, the only method available to experiments to incorporate the effect of the jet veto and the accompanying large logarithms beyond fixed order is to use parton-shower Monte Carlos, such as MC@NLO [32, 33], POWHEG [34, 35], Pythia [36, 37], and Herwig [38, 39].”

Study of the spin and parity of the Higgs boson in diboson decays with the ATLAS detector (2015, unknown): “The SM Higgs boson ggF production for all analyses is modelled using the Powheg-Box [27] generator at next-toleading order (NLO), interfaced toPythia 8 for parton showering and hadronisation and to simulate multi-parton interactions.”
