Two-loop amplitudes for processes $gg\to Hg,qg\to Hq$ and $q\bar{q}\to Hg$ at large Higgs transverse momentum

We compute the two-loop QCD corrections to amplitudes for processes $g g \to H g, q g \to H q$and$q \bar{q} \to H g$ in the limit when the Higgs transverse momentum is larger than the top quark mass, $p_{\perp }\gg m_t$. These amplitudes are important ingredients for understanding higher-order QCD effects on Higgs transverse momentum distribution at large $p_{\perp }$.
