abstract

The latest result from the ORGAN experiment, an axion haloscope is presented. This iteration of the experiment operated at millikelvin temperatures using a flux-driven Josephson parametric amplifier for reduced noise, along with various other improvements over previous iterations. Covering the $25.45 - 26.27\,\mu\text{eV}$ ($6.15-6.35$ GHz) mass (frequency) range, this near-quantum limited phase of ORGAN employs a conducting rod resonator and a 7-T solenoidal magnet to place the most sensitive exclusion limits on axion-photon coupling in the range to date, with $|g_{a\gamma\gamma}| \gtrsim 2.8\times10^{-13}$ at a 95\% confidence level.

  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. Detecting the Coupling of Axion Dark Matter to Neutron Spins at Spallation Sources via Rabi Oscillation

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A neutron-beam Rabi oscillation setup with double Stern-Gerlach spin selection could reach fa/Cn around 1.3e7 GeV and probe axion dark matter masses from 3e-13 to 1e-10 eV.

  4. Experiments to test the hypothesis for solar and dark matter axions

    hep-ph 2025-07 unverdicted novelty 1.0 of 10

    This is a pedagogical review of haloscope and helioscope experiments searching for dark matter and solar axions, with an overview of near-future technological developments.
