We identify a new production channel for QCD axions in supernova environments that contributes to axion emissivity for all models solving the strong CP problem. This channel arises at tree-level from a shift-symmetry-breaking operator constructed at next-to-leading order in Chiral Perturbation Theory. In scenarios where model-dependent derivative couplings to nucleons are absent, this sets the strongest model-independent constraint on the axion mass, improving on existing bounds by two orders of magnitude.

  1. Dark Matter Haloscope with a Disordered Dielectric Absorber

    hep-ph 2025-05 conditional novelty 7.0 of 10

    A disordered dielectric powder can act as a broadband dark-matter-to-photon conversion target, and the proposed DPHaSE experiment could probe QCD axions and dark photons in the 10 meV to 1 eV range.

  2. Constraining axion quadratic couplings with the Hulse-Taylor binary system

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Orbital timing of the Hulse-Taylor binary pulsar gives the strongest published limits on quadratic axion-muon couplings for axion masses below about 10^-12 eV, and complementary limits on axion-neutron and axion-elect...

  3. Probing Fundamental Constant Oscillation in the Galactic Center with S-Star Spectroscopy

    hep-ph 2025-07 conditional novelty 6.0 of 10

    Time-resolved spectroscopy of S-stars around Sgr A* can probe oscillations of the fine-structure constant induced by superradiant axion clouds or dark-matter soliton cores, with future instruments potentially reaching...

  4. Time-delayed gamma-ray signatures of heavy axions from core-collapse supernovae

    hep-ph 2024-12 conditional novelty 6.0 of 10

    No gamma-ray excess from four supernovae in Fermi-LAT data yields the strongest constraints yet on MeV-to-GeV heavy axions coupled to both QED and QCD.

  5. Heating the dark matter halo with dark radiation from supernovae

    hep-ph 2024-11 conditional novelty 6.0 of 10

    Even a few parts per million of supernova energy emitted as dark radiation could transform cuspy dwarf dark matter halos into cored ones, and observed core sizes bound how much energy can go to new particles.

  6. Axion Quality Problem: Keep Calm and Baryon

    hep-ph 2025-10 conditional novelty 5.0 of 10

    The QCD axion can be the Goldstone boson of baryon number in a minimal N_c=N_f supersymmetric QCD sector, with PQ-breaking effects suppressed by dimension N_c+2 operators.

  7. Detecting dilute axion stars constrained by fast radio bursts in the Solar System via stimulated decay

    hep-ph 2024-11 reject novelty 5.0 of 10

    The authors claim that a 50 MW radio beam can trigger a detectable radio echo from dilute axion stars in the Solar System, whose masses are constrained by fast radio bursts.
