Description
LUX-ZEPLIN (LZ) is a direct detection dark matter experiment that utilises a dual-phase time projection chamber (TPC) with 7 tonnes of active xenon at the Sanford Underground Research Facility in Lead, South Dakota. The experiment is primarily designed to detect interactions from weakly interacting massive particles (WIMPs), a well-motivated class of dark matter candidate. Following the establishment of the most stringent constraints on WIMP-nucleon scattering for masses between 9 GeV/c2 and 10 TeV/c2, LZ has completed a dedicated search for light dark matter in the 3-9 GeV/c2 mass range. The latter result, giving a world-leading limit at masses above 5 GeV/c2, will be the main focus of this talk. This analysis also includes our recent 4.5-sigma observation of solar ${}^{8}$B neutrinos via coherent elastic neutrino–nucleus scattering (CEνNS), demonstrating the sensitivity of large xenon detectors to keV-scale neutrino interactions and marking an important step toward the neutrino fog regime.
