Higgs boson decays h→MZ in the TNMSSM
Abstract
We study the SM-like Higgs boson decays $ h\rightarrow MZ $ in the triplet extended NMSSM (TNMSSM), where M is a vector meson $(\rho,\omega,\phi,J/\psi,\Upsilon)$ . Compared to the minimal supersymmetric standard model (MSSM), the TNMSSM includes two new $ S U$ (2) triplets with hypercharge ±1 and an SM gauge singlet, which are coupled to each other. The indirect contributions to the $ h\rightarrow MZ $ decays are produced from the effective $ h\gamma Z $ vertex, and they are more important than the direct contributions. The results of this work could encourage a detection on $ h\rightarrow Z\gamma $ at the future high energy colliders for exploring new physics beyond the SM. *Supported by the National Natural Science Foundation of China (NNSFC) (12075074, 12235008), Natural Science Foundation of Guangxi Autonomous Region (2022GXNSFDA035068), Hebei Natural Science Foundation (A2022201017, A2023201041), the youth top-notch talent support program of the Hebei Province
