We show that simple extensions of two higgs doublet models consisting of new heavy neutrinos and a singly charged Higgs boson singlet can successfully explain the experimental data on muon and electron anomalous magnetic moments thanks to large chirally-enhanced one-loop level contributions. These contributions arise from the large couplings of inverse seesaw neutrinos with singly charged Higgs bosons and right-handed charged leptons. The regions of parameter space satisfying the experimental data on (g −2) e,µ anomalies allow heavy singly charged Higgs boson masses above the TeV scale, provided that heavy neutrino masses are above few hundred GeV, the non-unitary part of the active neutrino mixing matrix must be large enough, two singly charged Higgs bosons are non degenerate, and the mixing between singly charged Higgs bosons must be non-zero.

“…Many models beyond the SM (BSM) have been constructed to explain the experimental data of (g − 2) µ,e , such as models adding vector-like lepton multiplets [8][9][10][11][12][13][14][15][16][17], leptoquarks [18], both neutral and charged Higss bosons as SU (2) L singlets [19]. Some two Higgs doublet models can give large two-loop contributions to ∆a µ from new SU (2) L Higgs doublets [20][21][22], where some of them require rather light masses of new neutral and/or charged Higgs bosons at few hundred GeV.…”

An explanation of experimental data of $(g-2)_{e,μ}$ in 3-3-1 models with inverse seesaw neutrinos

We will show that the anomalous magnetic moment experimental data of muon and electron (g − 2) µ,e can be explained simultaneously in simple extensions of the 3-3-1 models consisting of new heavy neutrinos and a singly charged Higgs boson. The heavy neutrinos generate active neutrinos masses and mixing through the general seesaw mechanism. They also have non-zero Yukawa couplings with singly charged Higgs bosons and right-handed charged leptons, which result in large one-loop contributions known as chirally-enhanced ones. Numerical investigation confirms a conclusion indicated previously that these contributions are the key point to explain the large (g − 2) µ,e data, provided that the inverse seesaw mechanism is necessary to allow both conditions that heavy neutrino masses are above few hundred GeV and non-unitary part of the active neutrino mixing matrix must be large enough.

In a simple extension of the standard model (SM), a pair of vector like lepton doublets (L1 and L2) and a SU(2)L scalar doublet (η) have been introduced to help in accommodating the discrepancy in determination of the anomalous magnetic moments of the light leptons, namely, e and μ. Moreover, to make our scenario friendly to a Dirac like neutrino and also for a consistent dark matter phenomenology, we specifically add a singlet scalar (S) and a singlet fermion (ψ) in the set-up. However, the singlet states also induce a meaningful contribution in other charged lepton processes. A discrete symmetry $$ {\mathcal{Z}}_2\times {\mathcal{Z}}_2^{\prime } $$ Z 2 × Z 2 ′ has been imposed under which all the SM particles are even while the new particles may be assumed to have odd charges. In a bottom-up approach, with a minimal particle content, we systematically explore the available parameter space in terms of couplings and masses of the new particles. Here a number of observables associated with the SM leptons have been considered, e.g., masses and mixings of neutrinos, (g − 2) anomalies of e, μ, charged lepton flavor violating (cLFV) observables and the dark matter (DM) phenomenology of a singlet-doublet dark matter. Neutrinos, promoted as the Dirac type states, acquire mass at one loop level after the discrete $$ {\mathcal{Z}}_2^{\prime } $$ Z 2 ′ symmetry gets softly broken, while the unbroken $$ {\mathcal{Z}}_2 $$ Z 2 keeps the dark matter stable. The mixing between the singlet ψ and the doublet vector lepton can be constrained to satisfy the electroweak precision observables and the spin independent (SI) direct detection (DD) cross section of the dark matter. In this analysis, potentially important LHC bounds have also been discussed.
