Abstract
BLMSSM is the extension of the minimal supersymmetric standard model(MSSM). Its local gauge group is . Supposing the lightest scalar neutrino is dark matter candidate, we study the relic density and the spin independent cross section of sneutrino scattering off nucleon. We calculate the numerical results in detail and find suitable parameter space. The numerical discussion can confine the parameter space and provide a reference for dark matter research.
