High - pT Higgs boson production at hadron colliders to O „ a sGF 3 ...

We study high-pT Higgs boson production in hadron collisions at one loop to order O(asGF 3 ). In particular, we investigate the process g1q( q̄)→q( q̄)1H , where q5u ,d ,c ,s , or b , for the CERN LHC ~a As514 TeV proton-proton collider!. Our results are compared to the O(as GF) and O(asGF) calculations. The associated production of a high-pT Higgs boson with a b quark or antiquark at O(asGF 3 ) is comparable to the O(as GF) and O(asGF) 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.
