Resumo

We propose a new mechanism of TeV scale leptogenesis where the chemical potential of right-handed electrons is passed on to the $B\ensuremath{-}L$ asymmetry of the Universe in the presence of sphalerons. The model has the virtue that the origin of neutrino masses is independent of the scale of leptogenesis. As a result, the model could be extended to explain dark matter, dark energy, neutrino masses, and leptogenesis at the TeV scale. The most attractive feature of this model is that it predicts a few hundred GeV triplet Higgs scalar that can be tested at LHC or the International Linear Collider.
