Naturally light right-handed neutrinos in a 3-3-1 Model
read the original abstract
In this work we show that light right-handed neutrinos, with mass in the sub-eV scale, is a natural outcome in a 3-3-1 model. By considering effective dimension five operators, the model predicts three light right-handed neutrinos, weakly mixed with the left-handed ones. We show also that the model is able to explain the LSND experiment and still be in agreement with solar and atmospheric data for neutrino oscillation.

The 3-3-1 Model: a natural framework for sub-MeV dark matter
The 3-3-1 model with right-handed neutrinos supplies a natural sub-MeV dark matter candidate as a gravitationally massive pseudo-Goldstone boson whose relic density is set by freeze-in at low reheating temperatures.

Heavy neutral bosons and dark matter in the 3-3-1 model with axionlike particle
In the 331ALP model the second Higgs is predicted above 600 GeV and the Z' above 5.1 TeV, with dark matter mass related to the axion breaking scale under a residual Z2 symmetry.
