Abstract

We compute next-to-leading order QCD corrections to the top-bottom interference contribution to H þ j production at the LHC. To achieve this, we combine the recent computation of the two-loop amplitudes for gg → Hg and qg → Hq, performed in the approximation of a small b-quark mass, and the numerical calculation of the squared one-loop amplitudes for gg → Hgg and qg → Hqg, performed within OPENLOOPS. We find that QCD corrections to the interference are large and similar to the QCD corrections to the topmediated Higgs production cross section. We also observe a significant reduction in the mass-renormalization scheme uncertainty once the next-to-leading order QCD prediction for the interference is employed.
