摘要：

We study the lightest Higgs boson decays h -> MZ in the mu from nu supersymmetric standard model (mu nu SSM), where M is a vector meson (rho, omega, phi, J/Psi, Upsilon). Compared to the minimal supersymmetric standard model (MSSM), the mu nu SSM 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 mu nu SSM can give large new physics (NP) contributions to the signal strengths of h -> MZ and h -> gamma gamma, which may be detected by a 100TeV collider or the other future high energy colliders.
