abstract

Differently from the canonical seesaw mechanism, which is grounded in grand unified theories, the inverse seesaw mechanism lacks a special framework that realizes it naturally. In this work we advocate that the 3-3-1 model with right-handed neutrinos has such an appropriate framework to accommodate the inverse seesaw mechanism. We also provide an explanation for the smallness of the $\mu$ parameter and estimate the branching ratio for the rare lepton flavor violation process $\mu \rightarrow e\gamma$.

  1. Leptoquark-induced radiative masses for active and sterile neutrinos within the framework of the 3-3-1 model

    hep-ph 2024-12 conditional novelty 6.0 of 10

    Adding one triplet and one singlet scalar leptoquark to the 331RHN model generates one-loop Majorana masses for active neutrinos and two-loop masses for sterile neutrinos, with benchmark parameters consistent with cur...

  2. LFV decays in a 3-3-1 model with singlet leptoquarks

    hep-ph 2026-07 conditional novelty 5.0 of 10

    In the 3-3-1 model with a singlet leptoquark, Higgs and Z lepton-flavor-violating decays are nearly proportional to radiative charged-lepton decays, and the model cannot produce large electron and muon magnetic anomal...

  3. Type-II Seesaw Mechanism for Dirac Neutrinos and its Implications on $N_{\text{eff}}$ and Lepton Flavor Violation in a 3-3-1 model

    hep-ph 2025-02 conditional novelty 5.0 of 10

    A scalar sextet generates eV-scale Dirac neutrino masses in a 3-3-1 model, and the associated right-handed neutrino population constrains the Z' boson mass to exceed 4.4 TeV.

  4. Heavy Neutral Leptons without Prejudice

    hep-ph 2024-12 conditional novelty 5.0 of 10

    HL-LHC and FCC-ee can probe HNL Yukawa couplings down to y^2 near 10^-4 to 10^-6 depending on mass; at zero mixing, Higgs width precision is the strongest constraint and the two colliders have comparable reach.

  5. Probing Dynamical Inverse Seesaw with Low-frequency Gravitational Waves

    hep-ph 2026-05 unverdicted novelty 4.0 of 10

    Dynamical inverse seesaw predicts low-frequency stochastic GW signals from a first-order phase transition, with complementarity to heavy neutral lepton searches at small active-sterile mixing.

  6. Dark Matter Freeze-In during Warm Inflation and the Seesaw Mechanism

    hep-ph 2024-12 conditional novelty 4.0 of 10

    A U(1)_{B-L} inverse-seesaw model realizes warm-inflation freeze-in of fermionic dark matter via a heavy Z' portal, with parameters adjusted to match the observed dark matter abundance and neutrino masses.

  7. Neutrino mass genesis in Scoto-Inverse Seesaw with Modular $A_4$

    hep-ph 2024-11 reject novelty 4.0 of 10

    The modular A4 scotogenic inverse seesaw model can fit normal-ordering neutrino data with a TeV-scale fermion dark matter candidate, but the stated parameter choice m_etaR = m_etaI makes the radiative neutrino mass vanish.

  8. Heavy neutral bosons and dark matter in the 3-3-1 model with axionlike particle

    hep-ph 2025-12 unverdicted novelty 3.0 of 10

    In the 331ALP model the second Higgs is predicted above 600 GeV and the Z' above 5.1 TeV, with dark matter mass related to the axion breaking scale under a residual Z2 symmetry.
