Description

The LUX-ZEPLIN (LZ) experiment is a Generation 2 multi-tonne dark matter direct detection experiment that will operate 4850 feet underground at the Sanford Underground Research Facility in Lead, South Dakota. It will use a 7 tonne liquid xenon TPC to search for the low energy recoils of xenon nuclei as they collide with our local galactic dark matter. LZ builds upon the demonstrated response to ~few keV nuclear recoils and the excellent self-shielding properties of liquid xenon and scales the TPC design beyond all existing and underway experiments. In addition, an optically separated and instrumented xenon skin layer (between the inner TPC and the walls of the cryostat) and a surrounding external liquid scintillator detector provide powerful rejection of gamma-rays and neutrons from internal sources. Materials screening and in-house purification of the liquid xenon then ensure that LZ meets the strict radioactivity constraints needed to achieve a WIMP search sensitivity to a spin independent cross section of 3E-48 cm^2 (at 40 GeV/c^2). With the construction phase well underway, LZ is on course to start physics data taking in 2020. In this talk I will give an overview of LZ, discuss the physics reach for both WIMPs and other non-WIMP signals, and present the current status of the experiment.
