“…(iii) The 3-3-1 models allow for the quantization of electric charge [107,108]. (iv) These models have several sources of CP violation [109,110]. (v) These models explain why the Weinberg mixing angle satisfies sin 2 θ W < 1 4 .…”

Abstract:We propose an extension of the 3-3-1 model with an additional symmetry group Z 2 × Z 4 × U(1) Lg and an extended scalar sector. To our best knowledge this is the first example of a renormalizable 3-3-1 model, which allows explanation the SM fermion mass hierarchy by a sequential loop suppression: tree-level top and exotic fermion masses, 1-loop bottom, charm, tau and muon masses; 2-loop masses for the light up, down, strange quarks as well as for the electron. The light active neutrino masses are generated from a combination of linear and inverse seesaw mechanisms at two loop level. The model also has viable fermionic and scalar dark matter candidates.

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.

“…However, the sterile neutrinos have small masses in the eV range. (Such ''miniseesaw'' models have been considered before, for a variety of reasons [27][28][29][30][31][32].) Vacuum mixing angles for oscillations between the active and sterile sectors are all fairly small.…”

We consider a model of neutrino oscillations with three additional sterile neutrinos and a gauged B-L interaction. We find allowed values of the model parameters which can reconcile the results of the evidence for ! e conversion seen at the LSND neutrino oscillation experiment with the null results of the MiniBooNE experiment. A portion of the low energy excess of e events seen at MiniBooNE can arise naturally, and we make a quantitative prediction for the forthcoming antineutrino oscillation results at MiniBooNE.

Concerning CP violation in 331 models

Abstract: We consider the implementation of CP violation in the context of 331 models. In particular we treat a model where only three scalar triplets are needed in order to give all fermions a mass while keeping neutrino massless. In this case all CP violation is provided by the scalar sector.
