Higgs bosons with large transverse momentum at the LHC
Abstract
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 q q bar → 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 q q bar → 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.
