Shh! These tests will enable a quieter search for dark matter

The LUX-ZEPLIN collaboration has published results showing radioactive background levels for experiment's components, creating a library for future rare event searches. The subatomic world just got a lot quieter for the LUX-ZEPLIN (LZ) dark matter experiment. Currently being assembled on the 4850 Level, 4850 feet below the surface at the Sanford Underground Research Facility, LZ will search for theoretical dark matter particles known as WIMPs, or weakly interacting massive particles.
