We compute the next-to-leading order QCD corrections to the production of Higgs bosons with large transverse momentum p?»2mt at the LHC. To accomplish this, we combine the two-loop amplitudes for processes gg?Hg, qg?Hq and qq¯?Hg, recently computed in the approximation of nearly massless top quarks, with the numerical calculation of the squared one-loop amplitudes for gg?Hgg, qg?Hqg and qq¯?Hgg processes. The latter computation is performed with OpenLoops. We find that the QCD corrections to the Higgs transverse momentum distribution at very high p? are large but quite similar to the QCD corrections obtained for point-like Hgg coupling. Our result removes one of the largest sources of theoretical uncertainty in the description of high-p? Higgs boson production and opens a way to use the high-p? region to search for physics beyond the Standard Model.
