Description
LUX-ZEPLIN (LZ) is a direct detection experiment located a mile underground at the Sanford Underground Research Facility in South Dakota, USA. LZ utilizes a dual-phase time projection chamber (TPC) with a 7-tonne active volume of liquid xenon. The TPC is surrounded by a veto system, composed of an instrumented liquid xenon skin and an outer detector with gadolinium-loaded liquid scintillator designed to tag neutron backgrounds. LZ has been collecting data since 2021 and in 2024 produced world-leading constraints on WIMP-nucleon cross-sections for WIMPs heavier than 9 GeV/c$^2$. In this presentation I will highlight LZ’s scientific results and provide an update on its status.
