02/09/2024 : Latest results for WIMP dark matter searches with LUX-ZEPLIN

LUX-ZEPLIN (LZ) is a direct dark matter detection experiment operating almost 1500m underground at the Sanford Underground Research Facility in Lead, South Dakota. At the heart of the experiment is a 7t dual-phase xenon time projection chamber. The TPC is surrounded by two veto detectors, a liquid xenon Skin and an Outer Detector consisting of Gd-loaded liquid scintillator tanks located inside an instrumented tank of ultra-pure water. Interactions with the xenon lead to scintillation and ionization signals that are recorded with two large PMT arrays. The large active mass as well as excellent background suppression capabilities give LZ unprecedented sensitivity to dark matter - nucleon interactions. I will report on the latest results from a search for weakly interacting massive particles (WIMPs) carried out by LZ, corresponding to an exposure of 280 live-days.
