“…In trying to recover the tribimaximal form in present work, by analysis a possibility close to the typical versions is when we replace the right-handed neutrinos by new standard model fermion singlets (N R ) with vanishing leptonnumber [12]. The resulting model is near that of our previous work in [5]. The neutrinos thus gain masses from only contributions of SU(3) L scalar antisextets.…”

We construct a 3-3-1 model based on family symmetry S 4 responsible for the neutrino and quark masses. The tribimaximal neutrino mixing and the diagonal quark mixing have been obtained. The new lepton charge L related to the ordinary lepton charge L and a SU (3) charge by L = 2 √ 3 T 8 + L and the lepton parity P l = (−) L known as a residual symmetry of L have been introduced which provide insights in this kind of model. The expected vacuum alignments resulting in potential minimization can origin from appropriate violation terms of S 4 and L. The smallness of seesaw contributions can be explained from the existence of such terms too. If P l is not broken by the vacuum values of the scalar fields, there is no mixing between the exotic and the ordinary quarks at the tree level.

“…A fascinating way seems to be the use of some discrete non-Abelian groups [3] as family symmetries added to the standard model gauge group. There is a series of models based on the group A 4 [4,5], T ′ [6], and more recently S 4 [7,8]-the group of permutations of four objects, which is also the symmetry group of the cube.…”

We discuss a 331 model with three scalar triplets and neutral fermion singlets. We show that in the 331 model with right-handed neutrinos, it is possible to obtain small active neutrino masses via the double and inverse seesaw mechanisms, without the use of scalar sextets or triplets with doubly-charged Higgs. Two types of models are discussed. If we have a large Majorana mass matrix for the singlets, the spectrum of neutrinos presents light, heavy and very heavy masses.The other possibility is a small (zero) Majorana mass matrix, which leads to pseudo-Dirac (Dirac) heavy neutrinos in the TeV scale, in addition to the active light neutrinos.

“…Furthermore, one can enforce some extra flavor symmetries in the lepton sector in order to dynamically get the appropriate PMNS mixing matrix. Some discrete groups, such as A 4 [47,48], S 4 [49] or S 3 [50,51] were employed in 3-3-1, and the procedure can be similarly applied in order to accomplish this task in the model of interest here.…”

Generating appropriate tiny neutrino masses via inverse seesaw mechanism within the framework of a particular SU (3)c ⊗ SU (4)L ⊗ U (1)X gauge model is the main outcome of this letter. It is achieved by simply adding three singlet exotic Majorana neutrinos to the usual ones included in the three lepton quadruplet representations. The theoretical device of treating gauge models with high symmetries is the general method by Cotăescu. It provides us with a unique free parameter (a) to be tuned in order to get a realistic mass spectrum for the gauge bosons and charged fermions in the model. The overall breaking scale can be set around 1-10 TeV so its phenomenology is quite testable at present facilities.
