Description
The LUX-ZEPLIN (LZ) dark matter search experiment, a dual-phase xenon time projection chamber operating at the Sanford Underground Research Facility in Lead, South Dakota, USA, has demonstrated the world's leading sensitivity to searches for Weakly Interacting Massive Particles (WIMPs). It comprises 7 tonnes of liquid xenon as an active target viewed by photomultiplier tubes (PMTs), xenon Skin and the outer detector (OD) made of gadolinium-loaded liquid scintillator. The Skin and the OD are also instrumented with PMTs and serve as veto systems against background events from radioactivity and cosmic muons. Beyond the standard spin-independent and spin-dependent WIMP interactions, LZ's exceptional sensitivity enables a comprehensive search for dark matter through a model-agnostic non-relativistic effective field theory (NR-EFT) framework, probing covariant Lagrangians arising from vector, axial, and dipole WIMP-nucleon couplings. This talk will highlight the results of the most recent LZ NR-EFT analysis.
