This study investigates the Higgs rare decays h0→ 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),ρ0,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 h0Zγ coupling can produce new physics(NP) contributions, thereby affecting the theoretical predictions of rare decays significantly through the new parameters such as κ, λ, λ2⋅⋅⋅. The results of this work can provide a reference for probing NP beyond standard model(SM).
