Description
The LUX-ZEPLIN (LZ) experiment has been searching since 2021 for a form of dark matter known as weakly-interacting massive particles (WIMPs). LZ consists of a time projection chamber containing 7 tonnes of liquid xenon and is surrounded by a multi-layer veto to help reject backgrounds, and is located at the Sanford Underground Research Facility in South Dakota. Recently, using a 5.7 tonne-year exposure, LZ has placed stringent limits on the spin-independent WIMP-nucleon cross section in the 3-9 GeV/c$^2$ WIMP mass range in the presence of coherent elastic neutrino-nucleus scattering (CE$\nu$NS) from $^8$B solar neutrinos. In this talk, I will review the LZ experiment and report on our recent science results. In particular, I will discuss the challenges associated with a near-energy-threshold search.
