主　　题：dark matter sneutrino supersymmetry 

摘      要：The BLMSSM is an extension of the minimal supersymmetric standard model(MSSM).Its local gauge group is SU(3)C×SU(2)L×U(1)Y×U(1)B×U(1)*** the lightest scalar neutrino is a dark matter candidate,we study the relic density and the spin independent cross section of sneutrino scattering off a *** calculate the numerical results in detail and find a suitable parameter *** numerical discussion can confine the parameter space and provide a reference for dark matter research.
