摘      要：As the U(1) extension of the minimal supersymmetric standard model, the U(1)XSSM has new super fields such as right-handed neutrinos and three Higgs singlets. In the U(1)XSSM, the lightest CP-even Higgs mass mh0is researched through the Higgs effective potential with one loop corrections. We also calculate the Higgs decays h0→ γγ , h0→ V V ( V = W, Z), h0→ ll¯Z and h0→ νν¯Z. The obtained results are reasonable, which are in favour of the study of the Higgs characteristic and the phenomenology of the U(1)XSSM. Copyright © 2022, The Authors. All rights reserved.
