TLDR
In this article, the authors compute the NLO virtual corrections to the partonic cross section of $gg\to HH$ in the high energy limit, where the Finite Higgs boson mass effects are taken into account via an expansion which is shown to converge quickly.Abstract:
We compute the NLO virtual corrections to the partonic cross section of $gg\to HH$, in the high energy limit. Finite Higgs boson mass effects are taken into account via an expansion which is shown to converge quickly. We obtain analytic results for the next-to-leading order form factors which can be used to compute the cross section. The method used for the calculation of the (non-planar) master integrals is described in detail and explicit results are presented.read more
