The low-scale approach to neutrino masses

Understand

In this short review we revisit the broad landscape of low-scale $SU(3)_c \times SU(2)_L \times U(1)_Y$ 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.
