New Constraints on Cosmic Ray-Boosted Dark Matter from the LUX-ZEPLIN Experiment Open
While dual-phase xenon time projection chambers have driven the sensitivity toward weakly interacting massive particles at the GeV/c2 to TeV/c2 mass scale, the scope for sub-GeV/c2 dark matter particles is hindered by a limited nuclear rec…
