* ABSTRACT | |||||||
We suggest a real right-handed sneutrino as a good dark matter candidate in a supersymmetric Z\' model realizing the seesaw mechanism. When the Z\' gaugino is light enough, the thermal freeze-out of the dark matter annihilation to right-handed neutrinos is shown to produce the right dark matter density. It is essential to include the decay and inverse decay of the right-handed neutrino in this process. At the LHC, the search for the dark matter can be made by observing the signatures of the Z\' gaugino decay to the right-handed neutrino and the dark matter producing same-sign dileptons plus large missing energy. |
