Axion-neutrino couplings and the effective neutrino mass

Abstract

In this work, we study the interaction between a complex neutral scalar boson, the axion and neutrinos, as a possible channel for the generation of the neutrino mass. We calculate one-loop corrections to the neutrino propagator and determine the value of the neutrino mass induced by the interactions with axions. We have obtained a set of relationships between the axion mass, the electron-neutrino mass and the strength of the coupling using current experimental limits on the nonobservation of the neutrinoless double beta decay.
