Description
We study the measurement of Higgs boson self-couplings through 2→3 vector boson scattering (VBS) processes in the framework of Standard Model effective field theory (SMEFT) at both proton and lepton colliders. The SMEFT contribution to the amplitude of the 2→3 VBS processes, taking WLWL→WLWLh and WLWL→hhh as examples, exhibits enhancement with the energy A(BSM)/A(SM)∼E^2/Λ^2, which indicates the sensitivity of these processes to the related dimension-six operators in SMEFT. Simulation and analysis of the full processes with backgrounds at future muon colliders are performed to constraint on c6 and cΦ1. The results are optimistic and comparable to di-Higgs production with 2->2 VBS.
