High-pT Higgs boson production at hadron colliders to O(αsGF3)

Abstract

We study high-pT Higgs boson production in hadron collisions at one loop to order O(αsGF3). In particular, we investigate the process g+q(q¯)→q(q¯)+H, where q=u,d,c,s, or b, for the CERN LHC (a √s=14 TeV proton-proton collider). Our results are compared to the O(αsGF3) and O(αsGF) calculations. The associated production of a high-pT Higgs boson with a b quark or antiquark at O(αsGF3) is comparable to the O(αsGF3) and O(αsGF) processes because of the large top quark mass and the additional contribution of electroweak gauge and Goldstone bosons. The associated production of light quarks, however, is not significant. We also comment on new physics effects in the framework of the electroweak chiral Lagrangian.
