TL;DR

The ADMX collaboration analyzed data from 2018 to search for axion dark matter within a specific mass range, successfully excluding certain axion models as the dominant dark matter component over most of that range.

Contribution

This paper provides a detailed account of the analysis process for ADMX Run 1B, including the specific analysis choices made for this data set.

Findings

01

Excluded DFSZ axions as the dominant dark matter over most of the searched frequency range.

02

Achieved a comprehensive analysis covering 680--790 MHz with detailed methodology.

03

Identified gaps due to mode crossings in the exclusion range.

Abstract

Searching for axion dark matter, the ADMX collaboration acquired data from January to October 2018, over the mass range 2.81--3.31 $μ$ eV, corresponding to the frequency range 680--790 MHz. Using an axion haloscope consisting of a microwave cavity in a strong magnetic field, the ADMX experiment excluded Dine-Fischler-Srednicki-Zhitnisky (DFSZ) axions at 100% dark matter density over this entire frequency range, except for a few gaps due to mode crossings. This paper explains the full ADMX analysis for Run 1B, motivating analysis choices informed by details specific to this run.
