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

Abstract

We compute the two-loop QCD corrections to amplitudes for processes $gg\to Hg,qg\to Hq$ and $q\bar{q}\to Hg$ 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 $p_{\perp }$.
