Next-to-leading order electroweak corrections to gg → HH and gg → gH in the large-mt limit


Davies, Joshua; Schönwald, Kay; Steinhauser, Matthias; Zhang, Hantian (2023). Next-to-leading order electroweak corrections to gg → HH and gg → gH in the large-mt limit. Journal of High Energy Physics, 2023(10):33.

Abstract

We compute two-loop electroweak corrections to Higgs boson pair and Higgs plus jet production, taking into account all sectors of the Standard Model. All diagrams with virtual top quarks are computed in an expansion for large top quark mass up to order 1/$$ {m}_t^8 $$ or more. We present analytic results for the form factors and discuss the convergence properties. For the process gg → gH we also consider QCD corrections in the large-m$_{t}$ limit.
