Lightest Higgs boson decays h → MZ in the μ from ν supersymmetric standard model

Abstract

Abstract We study the lightest Higgs boson decays h → MZ in the μ from ν supersymmetric standard model (μνSSM), where M is a vector meson (ρ, ω, ϕ, J/Ψ, Υ). Compared to the minimal supersymmetric standard model (MSSM), the μνSSM introduces three right-handed neutrino superfields, which lead to the mixing of the Higgs doublets with the right-handed sneutrinos. The mixing affects the lightest Higgs boson mass and the Higgs couplings. In suitable parameter space, the μνSSM can give large new physics (NP) contributions to the signal strengths of h → MZ and h → γγ, which may be detected by a 100 TeV collider or the other future high energy colliders.
