We study high-{ital p}{sub {ital T}} Higgs boson production in hadron collisions at one loop to order {ital O}({alpha}{sub {ital sG}}{sup 3}{sub {ital F}}). In particular, we investigate the process {ital g}+{ital q}({bar {ital q}}){r_arrow}{ital q}({bar {ital q}})+{ital H}, where {ital q}={ital u},{ital d},{ital c},{ital s}, or {ital b}, for the CERN LHC (a {radical}{ital s}=14 TeV proton-proton collider). Our results are compared to the {ital O}({alpha}{sup 3}{sub {ital sG}}{sub {ital F}}) and {ital O}({alpha}{sub {ital sG}}{sub {ital F}}) calculations. The associated production of a high-{ital p}{sub {ital T}} Higgs boson with a {ital b} quark or antiquark at {ital O}({alpha}{sub {ital sG}}{sup 3}{sub {ital F}}) is comparable to the {ital O}({alpha}{sup 3}{sub {ital sG}}{sub {ital F}}) and {ital O}({alpha}{sub {ital sG}}{sub {ital F}}) 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. {copyright} {ital 1996 The American Physical Society.}
