Electroweak Higgs boson pair production: Updated inclusive cross sections

TL;DR

This paper provides updated theoretical predictions for electroweak Higgs boson pair production cross sections at LHC energies, including higher-order quantum corrections, to aid experimental analyses.

Contribution

It offers the most recent inclusive cross section calculations at N$^3$LO QCD+NLO EW and NNLO QCD for various production modes, incorporating potential anomalous Higgs self-couplings.

Findings

Updated cross sections at N$^3$LO QCD+NLO EW for vector-boson fusion.

Updated cross sections at NNLO QCD for associated production with a vector boson.

Inclusion of anomalous Higgs self-coupling scenarios.

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.
