LUX-ZEPLIN detector logs single anomalous signal, hinting at possible dark matter hit

Scientists at the LUX-ZEPLIN experiment, which uses 10 tonnes of liquid xenon buried in South Dakota's Sanford Underground Research Facility, recorded one unusual flash consistent with a WIMP particle striking a xenon nucleus. The result, described in a preprint that has not yet been peer-reviewed, is far from confirmed but has generated excitement because it could represent the long-sought direct detection of dark matter.

LUX-ZEPLIN detector records single unexplained flash that could hint at dark matter

Researchers on the LUX-ZEPLIN experiment at South Dakota's Sanford Underground Research Facility reported a lone high-energy event in their 10-tonne liquid xenon detector, recorded sometime in 2023 or 2024, that matches the expected signature of a dark matter particle striking an atomic nucleus. The team announced the finding at a physics conference in Japan and posted details in a preprint, while cautioning that a single event is not proof.
