We propose a simple extension to the Standard Model, wherein neutrinos naturally attain small Majorana masses through a one-loop radiative mechanism featuring particles within the loops characterized by milli-charges. Unlike the conventional scotogenic model, our approach avoids imposing a discrete symmetry or expanding the gauge sector. The minuscule electric charges ensure the stability of the lightest particle within the loop as a viable dark matter candidate. Our investigation systematically scrutinizes the far-reaching phenomenological implications arising from these minuscule charges.

  1. Freeze-in Production of Non-Abelian Millicharged Vector Dark Matter

    hep-ph 2025-12 conditional novelty 6.0 of 10

    A hidden SU(2) gauge sector broken to a massless dark photon can produce vector dark matter via freeze-in with portal couplings near 10^-7.

  2. Searching for MeV-mass neutrinophilic Dark Matter with Large Scale Dark Matter Detectors

    hep-ph 2024-11 conditional novelty 4.0 of 10

    Xenon-based dark matter detectors, especially DARWIN, could detect neutrinos from MeV-mass dark matter that annihilates to the third neutrino mass eigenstate, with projected sensitivity competitive with Super-Kamiokande.
