Two-loop amplitudes for processes gg → Hg, qg → Hq and qq¯→Hg $$ \mathrm{q}\overline{\mathrm{q}}\to \mathrm{H}\mathrm{g} $$ at large Higgs transverse momentum
Abstract
Abstract We compute the two-loop QCD corrections to amplitudes for processes gg → Hg, qg → Hq and qq¯→Hg $$ q\overline{q}\to Hg $$ 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 ⊥.
