GoKawiilLUX-ZEPLIN detects unexplained particle event that may hint at dark matter
Researchers on the LUX-ZEPLIN (LZ) experiment, led in part by Brown University scientists, detected a single particle interaction consistent with a WIMP dark matter candidate of at least 200 GeV/c2 mass. The signal reached only 2.6-sigma statistical significance, far below the 5-sigma threshold needed to claim discovery, but stood out because background noise in that region is unusually low.
