abstract

We construct a viable 3-3-1 model with two $SU(3)_L$ scalar triplets, extended fermion and scalar spectrum, based on the $T^{\prime}$ family symmetry and other auxiliary cyclic symmetries, whose spontaneous breaking yields the observed pattern of SM fermion mass spectrum and fermionic mixing parameters. In our model the SM quarks lighter than the top quark, get their masses from a low scale Universal seesaw mechanism, the SM charged lepton masses are produced by a Froggatt-Nielsen mechanism and the small light active neutrino masses are generated from an inverse seesaw mechanism. The model is consistent with the low energy SM fermion flavor data and successfully accommodates the current Higgs diphoton decay rate and predicts charged lepton flavor violating decays within the reach of the forthcoming experiments.

  1. Multi-component Dark Matter in a Novel Three-Loop Inverse Scotogenic Seesaw Model

    hep-ph 2026-07 conditional novelty 6.0 of 10

    A three-loop inverse scotogenic seesaw with residual Z2⊗Z3 yields viable multi-component dark matter and approximate resonant leptogenesis while fitting neutrino and CLFV bounds.

  2. Natural neutrino sector in a 331-model with Froggatt-Nielsen mechanism

    hep-ph 2019-08 conditional novelty 6.0 of 10

    Adding right-handed neutrinos to the Froggatt-Nielsen 331 model realizes a double seesaw with sub-eV active neutrinos, keV sterile neutrinos, and TeV-scale heavy neutrinos that fits oscillation data in three benchmark points.
