Abstract

W±W±H production at hadron colliders through vector boson scattering is a so far unconsidered process, which leads to a clean signature of two same-sign charged leptons and two widely separated jets. This process is sensitive to the HHH and WWHH couplings and any deviation of these couplings from their SM predictions serves as direct evidence of new physics beyond the SM. In this paper we perform a Monte Carlo study of this process for the s√=14 TeV LHC and a 100 TeV pp-collider, and provide projections of the constraints on the triple-Higgs and WWHH quartic couplings for these environments. In particular, we consider the impact of pileup on the expected sensitivity in this channel. Our analysis demonstrates that although the sensitivity to the HHH coupling is rather low, the WWHH coupling can be constrained in this channel within ∼100% and ∼20% at 95\% confidence level around the SM prediction at the HL-LHC and a 100 TeV pp-collider, respectively.
