In the framework of BLMSSM, the Higgs decays h0→ Zγ and h0→ mVZ are studied where mV represents a vector meson(ρ, ω, ϕ, J/ψ, Υ etc.). Corrections to the CP-even and CP-odd h0γZ couplings occur via loop diagrams where new particles are involved. Actually both of them obviously influence the decay rates of h0→ Zγ and h0→ mVZ. Concretely, our obtained numerical result shows that the decay width of h0→ Zγ can be 1.3 times larger than the prediction of the Standard Model(SM). For the light mesons (ρ,ω), the corrections to h0→ mVZ are within 15%∼ 20% still consistent with the SM results. The results of this work would encourage a detection on h0→ Zγ at LHC for exploring new physics beyond SM.
