New Dark Matter Search Results from the LUX-ZEPLIN (LZ) Experiment
ORAL
Abstract
The LUX-ZEPLIN (LZ) experiment has been collecting data since 2021 to search for evidence of dark matter interactions using liquid xenon. The detector consists of a time projection chamber filled with 7 tonnes of xenon, surrounded by a veto system designed to reject radioactive backgrounds. The experiment is located at the Sanford Underground Research Facility in South Dakota and will record 1000 days of live time in the search for dark matter. Recently, the collaboration released results from a combined analysis using data from the WS2022 and WS2024 science campaigns, amounting to an exposure of 4.2 tonne-years. In this talk, I will describe the experiment and report on the status and latest results, which exclude spin-independent WIMP-nucleon cross sections down to a minimum of 2.2 x 10^{-48} cm^2 for a 43 GeV/cm^2 WIMP mass.
