Neutrino mixing matrix in the 3-3-1 model with heavy leptons and $A_4$ symmetry

Preprint English OPEN
Yin, Furong;

We study the lepton sector in the model based on the local gauge group $SU(3)_c\otimes SU(3)_L\otimes U(1)_X$ which do not contain particles with exotic electric charges. The seesaw mechanism and discrete $A_4$ symmetry are introduced into the model to understand why ne... View more
