Abstract: We compute the two-loop QCD corrections to amplitudes for processes gg → Hg, qg → Hq and q q ¯ → H g $q\overline{q}\to Hg$ in the limit when the Higgs transverse momentum is larger than the top quark mass, p ⊥ ≫ m t . These amplitudes are important ingredients for understanding higher-order QCD effects on Higgs transverse momentum distribution at large p ⊥ .
