abstract

We present a QCD axion model where the couplings of the axion to nucleons, electrons, and muons are naturally suppressed because of the appropriate choice of the Peccei-Quinn charges of the Standard Model fermions. We reexamine next-to-leading order corrections to the couplings of the axion with nucleons and photons and show that the axion decay constant may be as small as $10^7$ GeV. It is also possible to suppress the coupling with the photon so that the decay constant is even smaller and minimal axiogenesis works. In this scenario, the axion has a mass above 1 eV and may be directly detected via absorption of axion dark matter. Flavor-violating axion couplings are generically predicted in our model, but we show that they may be naturally and sufficiently suppressed. We discuss the implications of the hints for anomalous cooling in several stellar environments to our model.

  1. Dark Matter and Baryon Asymmetry from Monopole-Axion Interactions

    hep-ph 2025-11 conditional novelty 8.0 of 10

    A rotating QCD axion dissipates kinetic energy via dark monopole dyon transitions, explaining dark matter and baryon asymmetry with a predicted axion decay constant below 10^9 GeV.

  2. Axions on a Hyperbolic Ride: Geometric Suppression of CMB Isocurvature and a Blue-Tilted Spectrum

    hep-ph 2026-01 conditional novelty 6.0 of 10

    A hyperbolic PQ field-space metric exponentially suppresses CMB axion isocurvature and induces a blue-tilted spectrum, allowing H_inf≈10^13 GeV with fa up to 10^16 GeV.

  3. Improved cosmological constraints on axion-lepton interactions

    hep-ph 2025-11 conditional novelty 6.0 of 10

    For axion masses above 0.1 eV, cosmology provides the strongest known limits on axion couplings to muons, taus, and flavor-violating tau channels, excluding decay constants up to 10^8 GeV.

  4. Flipped Rotating Axion Non-minimally Coupled to Gravity: Baryogenesis and Dark Matter

    hep-ph 2025-02 conditional novelty 4.0 of 10

    A rotating axion, kicked into motion by a sign flip in its gravitational effective potential during kination, can co-generate baryon asymmetry and dark matter in a Majoron seesaw model.
