On September 1, 2026, the LUX-ZEPLIN (LZ) experiment team at the Sanford Underground Research Facility in South Dakota, USA, announced at the TeV Particle Astrophysics Conference that their detectors recorded an unexplained high-energy flash. The signal had an recoil energy of 248 kiloelectrons per volt, with a statistical significance of 2.6 sigma. Although it did not meet the 5-sigma confirmation threshold, known background sources were ruled out. LZ is conducted by 39 institutions and 250 scientists, using 10 tons of ultra-pure liquid xenon buried under a 1.6-kilometer-thick rock layer to capture the faint light signals produced by dark matter particle collisions. This discovery was peculiar due to the lack of expected low-energy accompanying signals, suggesting that dark matter may be more complex than current theories predict. Currently, the LZ team has submitted a paper and plans to analyze over 700 days of blind data. Experiments such as PandaX-4T and XENONnT will also help verify the results.
