“…There we clearly see that a scale of symmetry breaking around 2 TeV is favored. Our results are qualitatively consistent with previous works on this topic [14][15][16]22]. Complementary results coming from electroweak precision are discussed [57][58][59].…”

“…In this work we aim to explore the implications of the a μ anomaly on the reduced 3-3-1 model. This issue has been briefly addressed in [22], considering only contributions from the singly and doubly charged gauge bosons. In this work, we will derive analytical expressions for all 1-loop contributions coming from the reduced 3-3-1 model, and we will draw our conclusions based on the total contribution.…”

We study the muon anomalous magnetic moment (g − 2) μ in the context of the reduced minimal 3-3-1 model recently proposed in the literature. In particular, its spectrum contains a doubly charged scalar (H ±± ) and gauge boson (U ±± ), new singly charged vectors (V ± ) and a Z boson, each of which might give a sizeable contribution to the (g − 2) μ . We compute the 1-loop contributions from all these new particles to the (g − 2) μ . We conclude that the doubly charged vector boson provides the dominant contribution, and by comparing our results with the experimental constraints we derive an expected value for the scale of SU(3) L ⊗ U (1) N symmetry breaking v χ ∼ 2 TeV. We also note that, if the discrepancy in the anomalous moment is resolved in the future without this model then the constraints will tighten to requiring v χ 3.7 TeV with current precision, and they will entirely rule out the model if the expected precision is achieved by the future experiment at Fermilab.

“…Due to the lepton number violation, there are some specific channels of neutral Higgs decays into muon and tauon in the 3-3-1 model [18]. It was showed that in the RM331 model, bileptons enhance the channel Γ(h → γγ) and reduce the channel Γ(h → Zγ) [19]. At least, the RM331 model is able to explain the recent measurements of the LHC regarding the signal strength.…”

Abstract. At present, particle physics faces problems related with disparity in diphoton decay of Higgs boson, discrepancy between theory and experiment of about 3.6σ in anomalous magnetic moment of the muon and neutrino physics. Moreover, the existence of Dark Matter and the Matter-Antimatter Asymmetry are challenges for any physical model. In this review I present some solutions in the framework of the 3-3-1 models. The simple (by Higgs sector) models contain the hybrid inflationary scenario and the first-order phase transitions, from which leptogenesis needed for BAU is followed. By these considerations, some bounds on model parameters are derived.Keywords: particle-theory and field-theory models of the early Universe, supersymmetric models, non-standard-model neutrinos, right-handed neutrinos.

“…The 3-3-1 models have been considered in aspects of collider physics (Cieza Yue et al, 2013;Caetano et al, 2013), muon anomalous magnetic moments (Ky et al, 2000), neutrino physics (Dong et al, 2011), DM (Fregolente and Tonasse, 2003;.... In this review I will concentrate on Early Universe aspects of the models.…”

Abstract:We present status of the 3-3-1 models and their implications to cosmological evolution such as inflation, phase transitions and sphalerons. The models can deal not only with the issues such as neutrino physics, dark matter, etc, but they are also able to provide quite good agreement with the Standard Cosmology: The inflation happens at the GUT scale, while phase transition has two sequences corresponding two steps of symmetry breaking in the models, namely: SU(3) → SU(2) and SU(2) → U(1). Some bounds on the model parameters are obtained: in the RM331, the mass of the heavy neutral Higgs boson is fixed in the range: 285.56GeV < Mh2 < 1.746TeV and for the doubly charged scalar: 3.32TeV < Mh--< 5.61TeV.
