We consider Standard Model Higgs boson production in association with a W boson in hadron collisions. We supplement the fully exclusive perturbative computation of QCD radiative effects up to next-to-next-to-leading order (NNLO) with the computation of the decay of the Higgs boson into a bb pair at next-to-leading order (NLO). We consider the selection cuts that are typically applied in the LHC experimental analysis, and we compare our fixed-order predictions with the results obtained with the MC@NLO event generator. We find that NLO corrections to the H → bb decay can be important to obtain a reliable p T spectrum of the Higgs boson, but that, in the cases of interest, their effect is well accounted for by the parton shower Monte Carlo. NNLO corrections to the production process typically decrease the cross section by an amount which depends on the detail of the applied cuts, but they have a mild effect on the shape of the Higgs p T spectrum. We also discuss the effect of QCD radiative corrections on the invariant mass distribution of the Higgs candidate.

“…It is known that the gluon fusion-induced associated Higgs production [66][67][68], while only contributing ∼ 10% of the inclusive HZ production cross-section [69][70][71][72][73][74][75][76][77][78][79][80][81], becomes relevant at large momentum transfers due to the top quark threshold [58,59]. A similar argument applies to the non-decoupling of gg → H → ZZ at high momentum transfers [51,52,82].…”

We re-investigate electroweak signal-background interference in associated Higgs production via gluon fusion in the presence of new physics in the top-Higgs sector. Considering the full final state pp → bb + − ( = e, µ), we discuss how new physics in the top-Higgs sector that enhances the ZZ component can leave footprints in the HZ limit setting. In passing we investigate the phenomenology of a class of new physics interactions that can be genuinely studied in this process.

Abstract:We investigate the resummation effects for the SM Higgs and vector boson associated production at the LHC with a jet veto in soft-collinear effective theory using "collinear anomalous" formalism. We calculate the jet vetoed invariant mass distribution and the cross section for this process at Next-to-Next-to-Leading-Logarithmic level, which are matched to the QCD Next-to-Leading Order results, and compare the differences of the resummation effects with different jet veto p veto T and jet radius R. Our results show that both resummation enhancement effects and the scale uncertainties decrease with the increasing of jet veto p veto T and jet radius R, respectively. When p veto T = 25 GeV and R = 0.4 (0.5), the resummation effects reduce the scale uncertainties of the Next-to-Leading Order jet vetoed cross sections to about 7% (6%), which lead to increased confidence on the theoretical predictions. Besides, after including resummation effects, the PDF uncertainties of jet vetoed cross section are about 7%.
