“…There are interesting SUSY SU (5) models [45][46][47], which can very well reproduce the CKM and PMNS matrices in agreement with the experimental results, but where the simplicity in the matter content has been left aside. Most of these models include a large number of flavons, which are required to accommodate correctly the mixings.…”

We present a non-minimal renormalizable SUSY SU (5) model, with extended Higgs sector and right-handed neutrinos, where the flavor sector exhibits a Q 6 flavor symmetry. We analyzed the simplest version of this model, in which R-parity is conserved and the right-handed neutrino masses in the flavor doublet are considered with and without degeneracy. We find the generic form of the mass matrices both in the quark and lepton sectors. We reproduce, according to current data, the mixing in the CKM matrix. In the leptonic sector, in the general case where the right-handed neutrino masses are not degenerate, we find that the values for the solar, atmospheric, and reactor mixing angles are in very good agreement with the experimental data, both for a normal and an inverted hierarchy. In the particular case where the right-handed neutrinos masses are degenerate, the model predicts a strong inverted hierarchy spectrum and a sum rule among the neutrino masses. In this case the atmospheric and solar angles are in very good agreement with experimental data, and the reactor one is different from zero, albeit too small (θ th 13 ∼ 3.38 • ). This value constitutes a lower bound for θ 13 in the general case. We also find the range of the values for the neutrino masses in each case.

In this paper, we consider a neutrino mass model based on A 4 symmetry. The spontaneous symmetry breaking in this model is chosen to obtain tribimaximal mixing in the neutrino sector. We introduce Z 2 × Z 2 invariant perturbations in this model which can give rise to acceptable values of θ 13 and δ CP . Perturbation in the charged lepton sector alone can lead to viable values of θ 13 , but cannot generate δ CP . Perturbation in the neutrino sector alone can lead to acceptable θ 13 and maximal CP violation. By adjusting the magnitudes of perturbations in both sectors, it is possible to obtain any value of δ CP .

Lepton masses and mixings in a T′ flavored 3-3-1 model with type I and type II seesaw mechanisms

We propose a renormalizable T ′ flavor model based on the SU (3) C × SU (3) L × U (1) X × U (1) L gauge symmetry, consistent with the observed pattern of lepton masses and mixings.The small masses of the light active neutrinos are produced from an interplay of type I and type II seesaw mechanisms, which are induced by three heavy right-handed Majorana neutrinos and three SU (3) L scalar antisextets, respectively. Our model is only viable for the scenario of normal neutrino mass hierarchy, where the obtained physical observables of the lepton sector are highly consistent with the current neutrino oscillation experimental data. In addition, our model also predicts an effective Majorana neutrino mass parameter of m β ∼ 1.41541 × 10 −2 eV, a Jarlskog invariant of the order of J CP ∼ −0.032 and a leptonic Dirac CP violating phase of δ = 238 • , which is inside the 1σ experimentally allowed range.
