“…The bounds on the symmetry breaking scale are weaker in this case, though. Since existent limits from LHC physics on the ' Z mass (Coutinho et al, 2010) TeV . It is worth to be mentioned that this result truly complements previous results on ' Z mass (Coutinho et al, 2010) and shows the importance of CDM approach to electroweak precision phenomenology.…”

“…The data used in the exclusion curves were obtained using. Figure extracted from (Mizukoshi et al, 2011) Observe that these constraints are an important outcome concerning this 331LHN model, since the bounds on MZ ' obtained in (Coutinho et al, 2010) do not apply in the case m N ≤ M Z ' /2, where the main Z ' decay channel into charged leptons is suppressed due to this preferred invisible channel into two WIMPs. It is another complementary connection from dark matter that should be taken into account in the specific case where the heavy neutral fermion is the CDM candidate in 331LHN .…”

Abstract:In this study we review the cold dark matter problem in the context of a class of models which are a simple extension of the electroweak standard model, where the gauge symmetry is dictated by the group structure, SU(3) c ⊗SU(3)L⊗U(1) X . This model, in different versions, has been able to address many interesting facts not explained by the standard model. It would be just desirable that the dark matter issue could be contemplated as well, since the problem of the missing matter has become one of the greatest indications of incompleteness of currently established theories describing the known interactions and the cosmological evolution and content of the observed Universe. We do that by pointing out some of the successful steps in this direction and remarking some sources of difficulties concerning their phenomenological and theoretical implementation.

Neutrino Mass Mechanisms in 3-3-1 Models: A Short Review

In this study we review some mechanisms that provide light neutrinos in the framework of 3-3-1 gauge models without exotic leptons. In regard to the minimal 3-3-1 model, we call the attention to the fact that the perturbative regime of the model goes until 5 TeV. This requires alternative mechanisms in order to generate light neutrinos. In this review we discuss two mechanisms capable of generating light neutrinos in the framework of the minimal 3-3-1 model. In regard to the 3-3-1 model with right-handed neutrinos, we call the attention to the fact that in it mechanisms that generate light left-handed neutrinos also generate light right-handed neutrinos. Finally, we call the attention to the fact that the 3-3-1 model with right-handed neutrinos accommodate naturally the inverse seesaw mechanism.

“…Constraints from the heavy neutral Z of the model predict that this scale is of the order of the TeV scale [46]. Combining with the conditions of the minimum of the scalar potential, it can be deduced that both B/μ-terms and soft parameters should be of the same order, the electroweak O(m 2 W ) or the SU(3) L scale.…”

Higgs revised in supersymmetric economical 3-3-1 model with $$B/\mu $$ B / μ -type terms

We re-investigate the scalar potential and the Higgs sector of the supersymmetric economical 3-3-1 model (SUSYE331) in the presence of the B/μ-type terms, which has many important consequences. First, the model contains no massless Higgs fields. Second, we prove that the soft mass parameters of the Higgses must be at the SU(3) L scale. As a result, the masses of the Higgses drift toward this scale except one light real neutral Higgs with the mass of m Z |c 2γ | at the tree level. We also show that there are some Higgses containing many properties of the Higgses in the minimal supersymmetric standard model (MSSM), especially in the neutral Higgs sector. One exact relation in the MSSM, m 2 H ± = m 2 A + m 2 W , is still true in the SUSYE331. Based on this result we make some comments on the lepton flavor violating decays of these Higgses as one of signatures of new physics in the SUSYE331 model which may be detected by present colliders.
