Lightest Higgs boson decays $h\to MZ$ in the $\mu$ from $\nu$ supersymmetric standard model

Abstract

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