Three-loop corrections to Higgs boson pair production: reducible contribution
Joshua Davies, Kay Schönwald, Matthias Steinhauser, Marco Vitti
Abstract
A bstract We compute three-loop corrections to the process gg → HH originating from one-particle reducible diagrams. This requires the computation of two-loop corrections to the gluon-gluon-Higgs vertex with an off-shell gluon. We describe in detail our approach to obtain semi-analytic results for the vertex form factors and present results for the two form factors contributing to Higgs boson pair production.
