We aim to explain the nature of neutrinos using Peccei-Quinn symmetry. We discuss two simple scenarios, one based on a type-II Dirac seesaw and the other in a one-loop neutrino mass generation, which solve the strong CP problem and naturally lead to Dirac neutrinos. In the first setup latest neutrino mass limit gives rise to axion which is in the reach of conventional searches. Moreover, we have both axion as well as WIMP dark mater for our second set up.

  1. Axion framework with color-mediated Dirac neutrino masses

    hep-ph 2025-01 conditional novelty 5.0 of 10

    A KSVZ-type axion framework generates Dirac neutrino masses through colored vector-like quarks and leptoquarks, linking neutrino mass, strong CP, and dark matter.

  2. Dark matter from axion and small neutrino mass

    hep-ph 2024-12 conditional novelty 4.0 of 10

    A KSVZ-like model with a fermion dark matter candidate produced by UV freeze-in through the axion portal is shown to have viable parameter space at TeV mass and axion decay constant near 10^10 to 10^11 GeV.
