TL;DR
This paper reports a search for QCD axion dark matter around 3.3 μeV using an advanced haloscope with ultra low-noise amplification, excluding certain DFSZ axion masses with high confidence.
Contribution
The study demonstrates a sensitive experimental setup capable of excluding specific DFSZ axion masses in the 3.27 to 3.34 μeV range with high confidence.
Findings
Excluded DFSZ axions between 3.27 and 3.34 μeV at 90% confidence
Achieved sub-Kelvin noise temperatures with Josephson parametric amplifier
Set new limits on axion dark matter in the specified mass range
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 ultra low-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 eV, assuming a standard halo model with a local energy density of 0.45 GeV/cm made up 100% of axions.
