Higgs Production with Large Transverse Momentum in Hadronic Collisions at Next-to-Leading Order

Abstract

Inclusive associated production of a light Higgs boson (m H ≤ m t ) with one jet in pp collisions is studied in next-to-leading order QCD. Transverse momentum (p T ≥ 30 GeV) and rapidity distributions of the Higgs boson are calculated for the LHC in the large top-quark mass limit. It is pointed out that, as much as in the case of inclusive Higgs production, the K-factor of this process is large (≈ 1.6) and depends weakly on the kinematics in a wide range of transverse momentum and rapidity intervals. Our result confirms previous suggestions that the production channel p + p → H + jet → γ + γ + jet gives a measurable signal for Higgs production at the LHC in the mass range 100−140 GeV, crucial also for the ultimate test of the Minimal Supersymmetric Standard Model.13.85.-t, 14.80.Bm

NLO distributions for Higgs production at the LHC

“…yielding one-third of the total at large p T . The LO(sum) and NLO(sum) are slightly lower when m t is taken very large in which case we agree with the results in [ 11].…”

Next-to-leading order QCD corrections to five jet production at the LHC

“…The numerical size of the NLO corrections and the scale uncertainties at LO and NLO are comparable to what was observed in inclusive Higgs boson production in gluon fusion [48] or in the Higgs boson transverse momentum distribution in gluon fusion [49,50]. These processes are mediated through a heavy top quark loop and are very similar to the diphoton-plus-jet production considered here in terms of kinematics and initial-state parton momentum range.…”
