abstract

An axion dark matter search with the CAPP-8TB haloscope is reported. Our results are sensitive to axion-photon coupling $g_{a\gamma\gamma}$ down to the QCD axion band over the axion mass range between 6.62 and 6.82 $\mu$eV at a 90\% confidence level, which is the most sensitive result in the mass range to date.

  1. Catalogues of Cosmologically Self-Consistent Hadronic QCD Axion Models

    hep-ph 2024-12 conditional novelty 7.0 of 10

    Hadronic axion models with d=6 and d=7 heavy-quark decay operators can produce two new cosmologically viable 'islands' at f_a ~ 10^12 and 10^14 GeV, extending the post-inflationary axion search window.

  2. Axiverse Lampposts

    hep-ph 2026-02 conditional novelty 6.0 of 10

    In a hierarchical multi-axion theory with random couplings, axion field ranges shrink with 1/sqrt(N), generic axion–SM couplings are suppressed, but the QCD axion's coupling is unsuppressed.

  3. Probing the axion-electron coupling at cavity experiments

    hep-ph 2025-07 conditional novelty 6.0 of 10

    Cavity walls radiate microwave photons when axion dark matter generates a chiral magnetic current at the conductor surface, turning existing haloscope data into a bound on the axion-electron coupling g_ae ≲ 10^-5.

  4. Search for dark-matter axions beyond the quantum limit: the Cosmological Axion Sarov Haloscope (CASH) proposal

    hep-ph 2025-06 conditional novelty 6.0 of 10

    The CASH haloscope proposal projects that Josephson-junction single-photon detectors can reach axion-photon couplings below 1e-15 GeV^-1 in the 38-54 micro-eV mass range, beating the standard quantum limit.

  5. Dark Matter Nuclear Magnetic Resonance is Sensitive to Dark Photons and the Axion-Photon Coupling

    hep-ph 2025-05 conditional novelty 6.0 of 10

    CASPEr-Gradient, an NMR axion search, could simultaneously probe dark photon kinetic mixing to about 3e-16 and axion-photon coupling to about 2e-16 GeV^-1 near a mass of 1 micro-eV.

  6. Axion misalignment with memory-burdened PBH

    hep-ph 2025-01 conditional novelty 6.0 of 10

    Axion dark matter parameter space shifts dramatically when kinetic misalignment and memory-burdened primordial black hole evaporation are combined.

  7. Exploration of new experimental strategies for the detection of ultralight dark matter : laboratory searches on ground and in space

    hep-ph 2024-11 conditional novelty 6.0 of 10

    The thesis derives detailed theoretical sensitivities for several ultralight dark matter detection schemes, including a corrected dish-antenna model showing that focused power is much lower than previously assumed.

  8. Impact of First-order Electroweak Phase Transition on QCD Axion

    hep-ph 2025-07 conditional novelty 5.0 of 10

    A temporary axion mass spike during a first-order electroweak phase transition can make the QCD axion dark matter over a wide range of decay constants without a tuned initial angle.

  9. 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.

  10. Axion-like Particle Conversion in the Solar Magnetic Field

    hep-ph 2025-01 unverdicted

    A proceedings review that restates the ALP-photon conversion forecasts and NuSTAR limits from two previous papers, with no new results.

  11. Indirect detection of the QCD axion

    astro-ph.CO 2024-11 unverdicted

    A GBT X-band search for axion minicluster-neutron star radio transients in M31 found no 5-sigma candidates, yielding sensitivity to QCD axions in the 33-42 micro-eV mass range.
