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 …

We study the minimal set of Higgs scalars, for models based on the local gauge group SU
(3) c⊗ SU (3) L⊗ U (1) X, which do not contain particles with exotic electric charges. We …

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 …

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 …

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 …

Recently, Tsallis, Rényi, and Sharma‐Mittal entropies have widely been used to study the
gravitational and cosmological setups. We consider a flat FRW universe with linear …

We investigate simplified models involving an inert scalar triplet and vectorlike leptons that
can account for the muon g-2 anomaly. These simplified scenarios are embedded in a …

A bstract We propose an extension of the 3-3-1 model with an additional symmetry
group\({Z} _2\times {Z} _4\times\mathrm {U}{(1)} _ {L_g}\) and an extended scalar sector. To …

A bstract The ATLAS detector data on di-lepton production is used in order to impose
constraints on Z′ boson masses associated with a variety of 3-3-1 and E 6 motivated Z …

We have witnessed a persistent puzzling anomaly in the muon magnetic moment that
cannot be accounted for in the Standard Model even considering the existing large hadronic …
