Abstract

In this work, using the fact that in 3-3-1 models the same leptonic bilinear contributes to the masses of both charged leptons and neutrinos, we develop an effective operator mechanism to generate mass for all leptons. The effective operators have dimension five for the case of charged leptons and dimension seven for neutrinos. By adding extra scalar multiplets and imposing the discrete symmetry Z9⊗Z2 we are able to generate realistic textures for the leptonic mixing matrix. This mechanism requires new physics at the TeV scale.
