We study the SM-like Higgs boson decays h→MZ in the Triplet extended NMSSM (TNMSSM),where M is a vector meson (ρ, ω, ϕ, J/Ψ, Υ). Compared to the minimal supersymmetric standard model (MSSM), the TNMSSM includes two new SU(2) triplets with hypercharge ±1 and a SM gauge singlet which are coupled to each other. The indirect contributions to the decays h→MZ are produced from the effective hγZ vertex, and they are more important than the direct contributions. The results of this work would encourage a detection on h→Zγ at the future high energy colliders for exploring new physics beyond the SM.
