Sensitivity to triple Higgs couplings via di-Higgs production in the RxSM at the (HL-)LHC and future e + e − colliders

Abstract The real Higgs singlet extension of the Standard Model (SM) without Z 2 symmetry, the RxSM, is the simplest extension of the SM that features a First Order Electroweak Phase Transition (FOEWPT) in the early universe. The FOEWPT is one of the requirements needed for electroweak baryogenesis...
