Abstract：
We propose a new mechanism which can simultaneously explain tiny neutrino masses, stability of dark matter and baryon asymmetry of the Universe via leptogenesis from the common origin: a spontaneously breaking of a U(1)_X gauge symmetry at TeV scale. We discuss a simple renormalizable model to realize the above mechanism, and show the typical predictions of our scenario, which can be tested at future collider experiments.
