dc.description.abstract
We compute mixed QCD-weak corrections to inclusive Higgs production at the LHC from the partonic process gg→Hqq¯¯. We start from the UV- and IR-finite oneloop weak amplitude and consider its interference with the corresponding one-loop QCD amplitude. This contribution is a O(αsα) correction to the leading-order gluon-fusion cross section, and was not numerically assessed in previous works. We also compute the cross section from the square of this weak amplitude, suppressed by O(α2). Finally, we consider contributions from the partonic process gq → Hq, which are one order lower in αs, as a reference for the size of terms which are not enhanced by the large gluon luminosity. We find that, given the magnitude of the uncertainties on current state-of-the-art predictions for Higgs production, all contributions computed in this work can be safely ignored, both fully inclusively and in the boosted Higgs regime. This result supports the approximate factorisation of QCD and weak corrections to that process.
