Addendum to: Constraints on the quartic Higgs self-coupling from double-Higgs production at future hadron colliders

Wojciech Bizoń, Ulrich Haisch, Luca Rottoli +3

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…
