Abstract

U(1)X SSM is the extension of the minimal supersymmetric standard model (MSSM) and its local gauge group is SU(3)C× SU(2)L× U(1)Y× U(1)X . To obtain this model, three singlet new Higgs superfields and right-handed neutrinos are added to MSSM. In the framework of U(1)XSSM, we study the Higgs mass and take the lightest CP-even sneutrino as a cold dark matter candidate. For the lightest CP-even sneutrino, the relic density and the cross section for dark matter scattering off nucleon are both researched. In suitable parameter space of the model, the numerical results satisfy the constraints of the relic density and the cross section with the nucleon.
