abstract

We discuss an inverse seesaw model based on right-handed fermion specific $U(1)$ gauge symmetry and $A_4$-modular symmetry. These symmetries forbid unnecessary terms and restrict structures of Yukawa interactions which are relevant to inverse seesaw mechanism. Then we can obtain some predictions in neutrino sector such as Dirac-CP phase and sum of neutrino mass, which are shown by our numerical analysis. Besides the relation among masses of heavy pseudo-Dirac neutrino can be obtained since it is also restricted by the modular symmetry. We also discuss implications to lepton flavor violation and collider physics in our model.

  1. A Predictive Non-Holomorphic Modular $A_4$ Linear Seesaw Framework Testable at DUNE

    hep-ph 2026-02 conditional novelty 6.0 of 10

    A non-holomorphic modular A4 linear seesaw model with six singlet fermions and one flavon reproduces observed neutrino mixing and predicts absolute mass and 0νββ ranges that DUNE and other experiments can test.

  2. Phenomenology of Inverse Seesaw Using $S_3$ Modular Symmetry

    hep-ph 2025-04 conditional novelty 6.0 of 10

    A minimal S3 modular inverse seesaw model fits oscillation data and predicts inverted ordering, a massless lightest neutrino, and m_ee around 38 to 58 meV.

  3. 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.

  4. Matter-antimatter asymmetry in minimal inverse seesaw framework with $A_4$ modular symmetry

    hep-ph 2025-05 conditional novelty 3.0 of 10

    An A4 modular inverse seesaw model with a U(1) B-L Z' fits neutrino data and produces the observed baryon asymmetry via resonant leptogenesis.
