The light-fermion contribution to the exact Higgs-gluon form factor in QCD

“…This provides yet another indication that also for the total cross section, the QCD corrections are well described by their heavy-top limit. Also bottom-quark mass effects have been considered for finite p ⊥ [17,18] at this order of perturbation theory.…”

“…Indeed, a key observable for Higgs boson events is the number of jets produced in the event. For that reason, and since the Higgs p T distribution is sensitive to the production mechanism, there has recently been a growing interest, both experimentally [1][2][3][4][5][6] and theoretically [7][8][9][10][11][12][13][14][15], in the behavior of the Higgs p T distribution in inclusive and exclusive Higgs production, where the Higgs carries a substantial fraction of transverse momentum (for earlier work see [16][17][18][19]). In particular, the Higgs p T distribution in the exclusive Higgs þ jets production, pp → h þ nj, was one of the prime targets of the measurements performed recently by ATLAS and CMS [1][2][3][4][5][6].…”

“…(45) (r ggh is defined in Eq. (15) and therefore it also increases the statistical significance N SD by a factor of r ggh which depends on the p cut T used (see Fig. 3).…”

Fiducial cross sections for the four-lepton decay mode in Higgs-plus-jet production up to NNLO QCD

“…Recent progress in numerical calculations of two-loop matrix elements [40][41][42] enabled the calculation of the NLO QCD corrections to Higgs-plus-jet final states with full top quark mass dependence [16]. Analytical calculations of approximated massive two-loop matrix elements in [43][44][45] allowed detailed NLO phenomenology studies of top mass effects in the large transverse momentum limit [46] and of top-bottom interference effects in Higgs-plus-jet production at the LHC [47,48].…”
