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 {\mu}eV, assuming a standard halo model with a local energy density of
0.45 GeV/cc made up 100% of axions.
