Recent Results from the ADMX Axion Dark Matter Search Experiment

Abstract

We present recent results from the ADMX haloscope search for dark matter axions in the mass range $\rm{2.66-2.81\,\mu eV}$. In this mass range, assuming an axion dominated dark matter halo, we will exclude at 90\% confidence or discover axion-photon couplings predicted a range of plausible phenomenological axion models, including for the first time those predicted in the Dine-Fischler-Sredniki-Zhitnitsky (DFSZ) model. Ongoing searches will provide nearly definitive tests of the invisible axion model over a wide range of axion masses.
