“…The phenomenology of the model depends strongly on the numerical values of the matrices in Eq. (9), (10) and (11). To show this, in the Appendix A we present other parametrizations of the matrices and we discuss in the Conclusions how the constraint on the mass of the vector bilepton U ++ µ , coming from the decay µ → eeē, is affected when other parametrizations are used.…”

We consider the minimal 3-3-1 model with three sterile neutrinos transforming as singlet under the SU (3)L ⊗ U (1)X symmetry. This model, with or without sterile neutrinos, predicts flavor violating interactions in both quark and lepton sectors, since all the charged fermions mass matrices can not be assumed diagonal in any case. Here we accommodate the lepton masses and the Pontecorvo-Maki-Nakawaga-Sakata matrix at the same time, and as consequence the Yukawa couplings and the unitary matrices which diagonalize the mass matrices are not free parameters anymore. We study some phenomenological consequences, i.e., li → lj l klk and li → ljγ which are induced by neutral and doubly charged particles present in the model. In particular we find that if the decay µ → eeē is observed in the future, the only particle in the model that could explain this decay is the doubly charged vector bilepton.

“…We stress that even if neutrinos were massless (at tree level) the lepton flavor number is not conserved in this model. Here we will not consider neither CP violation, however see [11].…”

In this paper we present the mass matrices and mass eigenstates for the CPeven neutral scalars in the minimal 331 model (m331) and its self-interactions, showing that the m331 automatically reproduces the Higgs potential of the Standard Model. We also present a method to generate numerical solutions for the quarks and leptons masses and their mixings, which we apply to study FCNC processes, being to calculate the contributions of all exotic neutral particles of the m331 to the mass differences in meson oscillations.

“…These V l L,R matrices diagonalize the mass matrix in the following manner: V l L M l V l † R = diag(m e , m µ , m τ ). Possible solutions for the V l L,R matrices and the G l matrix can be found in [29] and [32]. To find these solutions it was considered |v ρ | = 54 GeV and |v η | = 240 GeV, as in Ref.…”

“…For more details of the model see Refs. [28] and [29]. An important issue, that in general cannot be neglected in 3-3-1 models, are the contributions of the scalars and pseudo-scalars, since sometimes there are important positive and/or negative interference with the amplitudes involving other particles in the model [30].…”

We calculate, in the context of a 3-3-1 model with heavy charged leptons, constraints on some parameters of the extra particles in the model by imposing that their contributions to both the electron and muon (g − 2) factors are in agreement with experimental data up to 1σ-3σ. In order to obtain realistic results we use some of the possible solutions of the left-and right-unitary matrices that diagonalize the lepton mass matrices, giving the observed lepton masses and at the same time allowing to accommodate the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) mixing matrix. We show that, at least up to 1-loop order, in the particular range of the space parameter that we have explored, it is not possible to fit the observed electron and muon (g − 2) factors at the same time unless one of the extra leptons has a mass of the order of 20-40 GeVs and the energy scale of the 331 symmetry to be of around 60-80 TeVs.
