  We consider Higgs boson production through gluon fusion at large transverse
momentum in hadronic collisions. We present the analytic expressions of the
relevant one-loop QCD amplitudes including the effects of the complete set of
dimension-six operators. The latter correspond to modifications of the top and
bottom Yukawa couplings, to an effective point-like Higgs coupling to gluons
and to the chromomagnetic operator of the top quark. The quantitative impact of
the chromomagnetic operator is also studied. Our results confirm previous
findings that the effect of the chromomagnetic operator at high $p_T$ can be
large and should not be neglected.
