Description

We discuss a TeV scale extension of the Standard Model in which a dark sector seeds neutrino mass generation radiatively within the linear seesaw mechanism. Since symmetry prevents tree-level contributions, tiny neutrino masses are generated at one-loop from spontaneous lepton number violation by the small vacuum expectation value of a Higgs triplet. The model can have sizeable rates for lepton flavour violating processes such as µ → eγ. We also comment on the implications for dark-matter and collider searches.
