“…For most of the values explored for the parameters, the contributions of the a 331 e increase the value of ∆a e . Other recent works have addressed the muon MDM in different but similar scenarios, in which smaller values for v χ and smaller masses for the extra particles were enough to explain the ∆a µ [6][7][8][9][10][11][12][13][14][15][16][17]. However, none of them have considered at the same time the contributions for the electron MDM from the particles and parameters that solve the muon MDM.…”

“…1. The muon MDM has been considered in the context of other 3-3-1 models in [6][7][8], however, there the authors did not consider the lepton mixing and also the constraints coming from the electron (g − 2) e . As can be seen in the matrices shown in Secs.…”

“…This difference between the SM prediction and the experimental value of the muon anomalous magnetic moment has been studied in many models. For instance, in other 3-3-1 models [6][7][8][9], left-right symmetric models [10], supersymmetric models [11][12][13][14][15] and two-Higgs doublets models [16,17].…”

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.

We find constraints on the highest scale of symmetry breaking of a model with gauge symmetryX with heavy neutral leptons in the fermion triplets, calculating the anomalous magnetic moment of the muon and using results of the relic abundance of dark matter and experiments searching for its direct detection.In order to do this, we have calculated the one-loop contribution of new particles in the model to (g − 2) µ , finding a favoured region for the scale at which SU (3) L is broken, and we have found lower bounds for this scale making a comparison of the predictions for the detection of a fermion dark matter candidate in the model in terms of simplified dark matter models, identifying the dominant portal for its interactions with standard model particles, and using constraints for the relic abundance and spin-independent scattering cross section of the fermion candidate with protons.

We sift the impact of the recent Higgs precise measurements, and recent dark matter direct detection results, on the dark sector of an electroweak extension of the Standard Model that has a complex scalar as dark matter. We find that in this model the Higgs decays with a large branching ratio into dark matter particles, and charged scalars when these are kinematically available, for any coupling strength differently from the so called Higgs portal. Moreover, we compute the abundance and spin-independent WIMP-nucleon scattering cross section, which are driven by the Higgs and Z boson processes. We decisively exclude the 1 − 500 GeV dark matter window and find the most stringent lower bound in the literature on the scale of symmetry breaking of the model namely 10 TeV, after applying the LUX-2013 limit. Interestingly, the projected XENON1T constraint will be able to rule out the entire 1 GeV-1000 GeV dark matter mass range. Lastly, for completeness, we compute the charged scalar production cross section at the LHC and comment on the possibility of detection at current and future LHC runnings.
