Abstract

We compute the two-loop QCD corrections to qg→Hq and qq-→Hg amplitudes mediated by loops of nearly massless quarks. These amplitudes provide the last missing ingredient required to compute the next-to-leading-order QCD corrections to the top-bottom interference contribution to the Higgs boson transverse momentum distribution at hadron colliders.
