Double Higgs boson production at NLO in the high-energy limit: complete analytic results

A bstract We compute the NLO virtual corrections to the partonic cross section of gg → 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 whic...

Description
Summary:A bstract We compute the NLO virtual corrections to the partonic cross section of gg → 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.
