abstract

We study one-loop induced radiative seesaw model applying a modular $A_4$ flavor symmetry, in which the neutrino mass matrix is achieved by two different Yukawa couplings one of which also contributes to positive value of muon anomalous magnetic moment as well as lepton flavor violations. Thanks to the specific mass matrix via $A_4$ symmetry and its modular weight, we find several predictions for lepton sector through our numerical analysis.

  1. Leptonic Flavor from Modular $A_4$: UV Mediators and SMEFT Realizations

    hep-ph 2025-05 conditional novelty 6.0 of 10

    This paper classifies lepton-coupled UV mediators under modular A4 symmetry and derives experimental lower bounds on their masses from lepton flavor observables.

  2. A modular $A_4$ symmetric scotogenic model

    hep-ph 2019-08 conditional novelty 6.0 of 10

    This paper builds a minimal scotogenic model with A4 modular symmetry and claims numerical predictions for CP phases, neutrino mass sum, and neutrinoless double beta decay that are consistent with current oscillation data.

  3. Neutrino mass model with a modular $S_4$ symmetry

    hep-ph 2019-08 conditional novelty 4.0 of 10

    A modular S4 radiative seesaw model fits normal-hierarchy neutrino data and predicts a total neutrino mass of roughly 58-62 meV and a double-beta decay mass of 1-4 meV.
