Description
LUX-ZEPLIN (LZ) is a dark matter direct detection experiment located at the Sanford Underground Research Facility in Lead, South Dakota. At the heart of the detector is a dual-phase time projection chamber containing 7~tonnes of active liquid xenon. With a combined exposure of 4.2~tonne-years from the first two science campaigns, LZ has placed the most stringent limits on spin-independent WIMP-nucleon cross section for WIMP masses above $5~\textrm{GeV}/\textrm{c}^{2}$, reaching $2.2 \times 10^{-48}~\textrm{cm}^{2}$ for a $40~\textrm{GeV}/\textrm{c}^{2}$ WIMP mass.
LZ has also provided the first $>3~\sigma$ evidence of coherent elastic neutrino-nucleus scattering from $^{8}B$ solar neutrinos. Most recently, LZ searched an extended nuclear-recoil energy window for effective field theory and inelastic dark matter models, observing one event consistent with a nuclear recoil energy of $248 \pm 23 (stat) \pm 23 (sys)~\textrm{keV}$ in a region with low expected background. In this talk, I will give an overview of the LZ experiment, discuss its status, and report on its latest results in the search for dark matter and other rare phenomena.
