| contents | This study investigates the Higgs rare decays $h^0\rightarrow Zγ,V Z$ within the next to minimum B-L supersymmetric model(NB-LSSM), where $V$ represents a vector meson $(ϕ,J/ψ,Υ(1S),ρ^0,ω)$. Compared to the minimal supersymmetric standard model(MSSM), the NB-LSSM introduces three singlet Higgs superfields, which mix with the Higgs doublets and affect the lightest Higgs boson mass and the Higgs couplings. The loop-induced contributions resulting from the effective $h^0Zγ$ coupling can produce new physics(NP) contributions, thereby affecting the theoretical predictions of rare decays significantly through the new parameters such as $κ$, $λ$, $λ_2\cdot\cdot\cdot$. The results of this work can provide a reference for probing NP beyond standard model(SM). |
