【 摘 要 】

Neutrino mass may be linked to dark matter through a well-studied radiative (scotogenic) mechanism. The new particles required are just right for the extension of the well-known SU(5) unification of quarks and leptons to include dark matter. Two examples are discussed: SU(6) which incorporates a discrete Z2symmetry for dark matter, and SU(7) which allows for a gauge U(1)Dsymmetry. In either case, just as the proton is not absolutely stable within the context of SU(5), dark matter is also not absolutely stable within SU(6) or SU(7).
