Search for "Invisible" Axion Dark Matter in the $3.3\text{-}4.2\mu$eV Mass Range

ADMX Collaboration, C. Bartram, T. Braine +49

We report the results from a haloscope search for axion dark matter in the $3.3\text{-}4.2\mu$eV mass range. This search excludes the axion-photon coupling predicted by one of the b…
