Description
We study the lightest Higgs boson decays $h\rightarrow Z\gamma$, $h\rightarrow MZ$ in the $\mu$ from $\nu$ supersymmetric standard model ($\mu\nu$SSM), where M is a vector meson ($\rho,\omega,J/\psi, \Upsilon$). 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\rightarrow Z\gamma$$h\rightarrow MZ$ and $h\rightarrow \gamma\gamma$, which may be detected by a 100 TeV collider or the other future high energy colliders.
