Fundamentals of the 3-3-1 model with heavy leptons

This work is a brief presentation of the theory based on the ##IMG## [http://ej.iop.org/images/0954-3899/45/4/043001/jpgaaabd5ieqn1.gif] {${SU}{(3)}_{c}\,\otimes {SU}{(3)}_{L}\otimes U{(1)}_{X}$} gauge group in the presence of heavy leptons. Recent studies [1] have considered a set of four possible variants for the 3-3-1HL, whose content arises according to the so-denoted variable β . Since it has been argued about the presence of stable charged particles in this sort of model, we divide the different sectors of the Lagrangian between universal and specific vertices, and conclude that the omission of β -dependent terms in the potential may induce discrete symmetry for the versions defined by ##IMG## [http://ej.iop.org/images/0954-3899/45/4/043001/jpgaaabd5ieqn2.gif] {$| \beta | =\sqrt{3}$} . In the context of ##IMG## [http://ej.iop.org/images/0954-3899/45/4/043001/jpgaaa...] {$| \beta | =\tfrac{1}{\sqrt{3}}$}
