Electroweak Higgs boson pair production: Updated inclusive cross sections

Ramona Gröber, Alexander Karlberg, Mathieu Pellen, Gioia Sacchi, Michael Spira

Abstract

We present updated inclusive cross sections for electroweak Higgs boson pair production for energies of relevance to the LHC and High-Luminosity phase of the LHC. The cross sections are presented at N$^3$LO QCD+NLO EW for vector-boson fusion and NNLO QCD for associate production with a vector boson. We compute the cross sections using the most up-to-date theory inputs, both in the Standard Model and for a few anomalous values of the trilinear Higgs self-coupling.
