Neutrino Decay and Neutrinoless Double Beta Decay in a 3-3-1 Model

Abstract

In this work we show that the implementation of spontaneous breaking of the lepton number in the 3-3-1 model with right-handed neutrinos gives rise to fast neutrino decay with majoron emission and generates a bunch of new contributions to the neutrinoless double beta decay.
