Addendum to: Constraints on the quartic Higgs self-coupling from double-Higgs production at future hadron colliders
Abstract:
We study inclusive double-Higgs boson production at the LHC and at the HL-
LHC including variations of the trilinear and of the quartic Higgs boson self-couplings at
next-to-leading order (NLO) in QCD with full top quark mass dependence. Our results
include the two-loop contributions to the gg → HH amplitudes that involve a modified h4
vertex calculated in ref. [ 1 ]. We present results at 13, 13.6 and 14 TeV centre-of-mass energies.
The implementation of the calculation is made publicly available in the POWHEG-BOX-V2
Monte Carlo framework.
