First Limits on Axion Dark Matter from a DALI Prototype

High Energy Physics - Experiment 2026-03-24 v1

Abstract

We report a pilot dark-matter search with a cryogenic, magnetized, scaled-down DALI prototype. An analysis of 36 hours of data reveals no statistically significant excess attributable to axionlike particles. We therefore set new exclusion limits in the 6.883--6.920 GHz band, reaching an axion-photon coupling sensitivity of gaγγ1.27×1011GeV1g_{a\gamma\gamma}\lesssim 1.27\times10^{-11}\,\mathrm{GeV}^{-1} at 28.54 μ\mueV. These results consolidate the DALI approach and motivate a next-stage haloscope to explore a broader mass range with upgraded instrumentation.
