Recent Results from LZ

The LUX-ZEPLIN (LZ) experiment is a dark matter direct detection experiment that uses a 7 active-tonne dual-phase xenon time projection chamber (TPC) to primarily search for weakly interacting massive particles (WIMPs), a well-motivated candidate for dark matter. The TPC is surrounded by a three-component veto system and located nearly a mile underground at the Sanford Underground Research Facility in Lead, South Dakota, aiming to reduce internal and external backgrounds. LZ has been actively collecting physics data since late 2021, with the first science run (WS2022) being used to set unprecedented limits on WIMP-nucleon interactions, and the analysis of the second one (WS2024) freshly finished and presented. Besides some general notions about the experiment and its current status, this seminar will mainly focus on showing this latest result, the principal features of the corresponding analysis, and the major differences with respect to the previous WS2022 search.
