Minimal Dynamical Inverse See Saw

We present a minimal model in which the Inverse See Saw is realized dynamically. The two unity lepton number breaking term is induced at two-loop level and is naturally around the keV scale, while right-handed neutrinos are at the TeV scale. An interesting extension of the model is obtained by gauging B-L: in this case anomaly cancellation has as direct consequence the presence of a sterile neutrino at the MeV scale that may be a good Dark Matter candidate. Moreover the new gauge boson Z' and the new neutral scalars may have characteristic signatures at LHC.
