Abstract 摘要	I review briefly the motivation for supersymmetry, and for extending the gauge symmetry by an extra U(1), consistent with symmetry breaking from E6 SUSY GUT. Imposing universality conditions from the GUT scale, and using experimental constraints, I perform a scan of the parameters of the model. Both the right-handed sneutrino and the lightest neutralino can serve as DM candidates. Constraints from cosmic abundance and direct detection restrict the parameter space in each case. Finally, I discuss the possibility of observing signals of such models at the LHC. In particular, chargino pair production leading to 2 leptons and missing energy can yield significant signal to background enhancements.
