A new idea for neutrino mass was proposed recently, where its smallness is not due to the seesaw mechanism, i.e. not inversely proportional to some large mass scale. It comes from a one-loop mechanism with dark matter in the loop consisting of singlet Majorana fermions Nᵢ with masses of order 10 keV and neutrino masses are scaled down from them by factors of about 10⁻⁵. We discuss how this model may be implemented with the non-Abelian discrete symmetry A₄ for neutrino mixing, and consider the phenomenology of Nᵢ as well as the extra scalar doublet (η+,η⁰).
