ADMX axion dark matter bounds around 3.3  μeV with Dine-Fischler-Srednicki-Zhitnitsky discovery ability

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 μ⁢eV, assuming a standard halo model with a local energy density of 0.45 G⁡e⁢V/cm3 made up 100% of axions.

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 μ⁢eV, assuming a standard halo model with a local energy density of 0.45 G⁡e⁢V/cm3 made up 100% of axions.
