A detailed and general study of the fermionic structure of the 331 models with β arbitrary is
carried out based on the criterion of cancellation of anomalies. We consider models with an …

A complete study of the Higgs sector of the SU (3) c⊗ SU (3) L⊗ U (1) X model is carried out,
obtaining all possible cases of vacuum expectation values that permit the spontaneous …

We have witnessed some flavor anomalies appearing in the past years, and explanations
based on extended gauge sectors are among the most popular solutions. These beyond the …

The SU (3) C⊗ SU (3) L⊗ U (1) X gauge model with the minimal scalar sector (two Higgs
triplets) is studied in detail. One of the vacuum expectation values u is a source of lepton …

In this paper we compute all contributions to the muon magnetic moment stemming from
several 3-3-1 models, namely, minimal 331, 331 with right-handed neutrinos, 331 with …

We propose two 3-3-1 models (with either neutral fermions or right-handed neutrinos) based
on S 3 flavor symmetry responsible for fermion masses and mixings. The models can be …

In the context of the 331 models, we consider constraints on the extra neutral boson Z′
predicted by the model, where three different quark family assignments are identified. Using …

We show that the SU (3) C⊗ SU (3) L⊗ U (1) X (3-3-1) model of strong and electroweak
interactions can naturally accommodate an extra U (1) N symmetry behaving as a gauge …

Some 3-3-1 models predict the existence of a non-perturbative regime at the TeV scale. We
study in these models and their supersymmetric extensions, the energy at which the non …

By introducing local ZN symmetries with N= 11, 13 in two 3-3-1 models, it is possible to
implement an automatic Peccei-Quinn symmetry, kee** the axion protected against …
