They have stopped well short of claiming an actual detection, but the researchers involved are calling it the most compelling hint reported to date. The signal was recorded at the Sanford Underground Research Facility, built inside a former gold mine in South Dakota's Black Hills region and managed by the US Department of Energy's Lawrence Berkeley National Laboratory. The location is deliberate rather than incidental. Sitting roughly 1.6 kilometres underground shields the experiment's detector from cosmic rays and other background radiation that would otherwise drown out the extremely faint signal researchers are actually looking for. The experiment itself, called LUX-ZEPLIN, uses 10 tonnes of ultrapure liquid xenon to catch the rare interactions a dark matter particle would theoretically produce if it collided with ordinary matter. In June, the detector recorded a single flash of energy now designated LZ230616, a particle interaction that may have involved a hypothesised particle called a WIMP, short for weakly interacting massive particle, one of the leading theoretical candidates for what dark matter actually is. The finding was presented at the 2026 TeV Particle Astrophysics conference in Japan and posted to the arXiv preprint server for other physicists to scrutinise. --- *This article is only available to registered readers.
