摘要：
As the U(1) extension of the minimal supersymmetric standard model, the U(1)(X)SSM has new superfields, such as right-handed neutrinos, and three Higgs singlets. In the U (1)(X)SSM, the lightest CP-even Higgs mass m h o is studied by using the Higgs effective potential with one-loop corrections. We also calculate the Higgs decays h(0) -> gamma gamma, h(0) -> VV (V = W, Z), h(0) -> l (l) over barZ, and h(0) -> nu(nu) over barZ. The obtained results are reasonable, and they are in favor of the study of the Higgs characteristic and the phenomenology of the U(1)(X)SSM.
