We compute the next-to-next-to-leading order QCD corrections to Higgs boson production in weak boson fusion followed by its decay to a b b pair or to a pair of leptonically-decaying W bosons.Our calculation allows us to compute realistic fiducial cross sections and assess the impact of fiducial cuts applied to the Higgs boson decay products on the magnitude of QCD radiative corrections in weak boson fusion.

“…However, for the currently-available state of the art, one would consider these processes to be theoretically accurate and precisely modeled at NLO QCD, at least within the typical region of VBS acceptance. The merging of different jet multiplicities has recently been addressed in VBF Higgs production [9,10], and detailed studies of parton shower effects are available in these cases [11,12], suggesting that the perturbative component is mostly well under control, though [10] has in fact pointed out that the role of the VBF approximation in shower initial conditions for multi-jet merging might be more delicate than naively expected.…”

We consider the impact of multi-parton interactions, colour reconnection and hadronization on the modeling of vector boson fusion and vector boson scattering (VBS) final states at the Large Hadron Collider (LHC). We investigate how the variation of the model parameters, compatible with a reasonable spread of predictions around typical tuning observables, extrapolates into the VBS phase space. We study the implications of this variation on the total uncertainty budget attached to realistic simulation of the final states in current event generator predictions. We find that the variations have a non-trivial phase space dependence and become comparable in size to the perturbative uncertainties once next-to-leading order predictions are combined with parton shower evolution.1 Exceptions of this kind are newly developed evolution algorithms at the amplitude level, see e.g. [8].

“…Both in the inclusive case and for the production in association with jets, the dominant Higgs production mode in the SM originates via a top-quark loop in gluon-gluon fusion, however, at large transverse momentum eventually also vector-boson fusion (VBF), Higgsstrahlung (VH) and top-pair associated Higgs production contribute significantly [15]. For the production in association with jets, additional constraints on jet invariant masses and/or rapidities allow the relative fraction of the VBF events to be enhanced [16,17]. Precise VBF measurements will allow us to constrain on the one hand the electroweak (EW) couplings of the Higgs, and on the other hand when restricting to large Higgs transverse momentum they will allow for complementary constraints on models of new physics [18][19][20][21][22][23].…”

We present calculations of Higgs boson production via gluon-gluon fusion in association with one or two additional jets at next-to-leading order in QCD. The calculation of H+jet is exact in the treatment of the top-quark mass, whereas for the H+2 jets calculation the two-loop virtual amplitudes are approximated via a reweighting with leading-order mass effects, while keeping all top-quark mass effects in the real radiation contributions. For H+jet production, this study extends a previous calculation, revealing an error in the previous results. For total and differential cross sections, we present new results and compare the QCD corrections with the infinite top-mass limit, for which we find a strikingly good agreement if all amplitudes are rescaled by the leading-order mass dependence.
