I n the continuing game of dark matter hide-and-seek, new results from two experiments have helped the collaborations behind them rule out further hiding places for the elusive substance [1, 2]. The results come a year after the team behind another dark matter experiment reported tantalizing signals that could be interpreted as evidence for a hypothesized dark matter particle called an axion (see Viewpoint: Dark Matter Detector Delivers Enigmatic Signal). With neither of the new results…

TLDR
A haloscope search for axiondark matter in the 3.3-4.2  μeV mass range excludes the axion-photon coupling predicted by one of the benchmark models of "invisible" axion dark matter, the Kim-Shifman-Vainshtein-Zakharov model.
