【 摘 要 】

We present a U(1) extension of the standard model that accounts after breaking for the small neutrino masses and the observed dark matter abundance. From the presence of the dark matter candidate, an original scenario of leptogenesis emerges, viable in a restricted region of the parameter-space. Relying on a rich scalar sector, this model can deviate from standard model Higgs phenomenology.
