Abstract

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