Goodman, C., Guzzetti, M., Hanretty, C. et al. (46 more authors) (2025) ADMX axion dark matter bounds around 3.3 μeV with Dine-Fischler-Srednicki-Zhitnitsky discovery ability. Physical Review Letters, 134 (11). 111002. ISSN 0031-9007
Abstract
We report the results of a QCD axion dark matter search with discovery ability for Dine-Fischler-Srednicki-Zhitnitsky (DFSZ) axions using an axion haloscope. Sub-Kelvin noise temperatures are reached with an ultralow noise Josephson parametric amplifier cooled by a dilution refrigerator. This work excludes (with a 90% confidence level) DFSZ axions with masses between 3.27 to 3.34 μeV, assuming a standard halo model with a local energy density of 0.45 GeV/cm3 made up 100% of axions.
