Abstract

We compute the next-to-leading order QCD corrections to the production of Higgs bosons with large transverse momentum p2mtp_\perp \gg 2 m_t at the LHC. To accomplish this, we combine the two-loop amplitudes for processes ggHggg \to Hg, qgHqqg \to Hq and qqˉHgq \bar q \to H g, recently computed in the approximation of nearly massless top quarks, with the numerical calculation of the squared one-loop amplitudes for ggHgggg \to Hgg, qgHqgq g \to H q g and qqˉHggq \bar q \to Hgg processes. The latter computation is performed with OpenLoops. We find that the QCD corrections to the Higgs transverse momentum distribution at very high pp_\perp are large but quite similar to the QCD corrections obtained for point-like HggHgg coupling. Our result removes one of the largest sources of theoretical uncertainty in the description of high-pp_\perp Higgs boson production and opens a way to use the high-pp_\perp region to search for physics beyond the Standard Model.
