Description
The LUX-ZEPLIN (LZ) experiment is located at the Sanford Underground Research Facility in Lead, South Dakota. LZ is primarily designed to detect interactions of dark matter in the form of weakly-interacting massive particles (WIMPs) using a 7 tonne dual-phase xenon time projection chamber (TPC). LZ has been acquiring science data since 2021 under stable operating conditions. Now, with a combined exposure of 4.2 tonne-years from all science campaigns, LZ has placed the most stringent limits on spin-independent WIMP-nucleon cross section down to $2.2 \times 10^{-48}$ cm$^2$ for a 43 GeV/c$^2$ WIMP mass. In this talk I'll present the current status of the LZ experiment and its latest dark matter search results.
