The Low-Scale Approach to Neutrino Masses

Abstract

In this short review we revisit the broad landscape of low-scale SU(3)c⊗SU(2)L⊗U(1)Y models of neutrino mass generation, with view on their phenomenological potential. This includes signatures associated to direct neutrino mass messenger production at the LHC, as well as messenger-induced lepton flavor violation processes. We also briefly comment on the presence of WIMP cold dark matter candidates.
