Dark Matter Search Achieves New Record and Spots Neutrinos From Sun’s Core

Dark matter search achieves new record and spots neutrinos from Sun’s core

12.12.2025 - The LUX-ZEPLIN (LZ) collaboration involving UCL researchers has achieved a new record in its search for dark matter and for the first time picked up signals from neutrinos produced in the Sun's core, a milestone in sensitivity.

LZ detector marks a new era in the search for light dark matter and neutrinos

Far beneath the Black Hills of South Dakota, a tank of liquid xenon is quietly recording some of the faintest signals in the universe. In that deep, quiet space, researchers have pushed their instrument to do two jobs at once. It has tightened the net around one possible form of light dark matter and, at the same time, captured strong evidence of rare scattering from neutrinos produced in the sun. The experiment, called LUX-ZEPLIN, or LZ, sits n…
