Abstract

The LUX-ZEPLIN (LZ) experiment is a direct detection search for thermal WIMP dark matter. Its WIMP target consists of seven fully active tonnes of liquid xenon (LXe) within an instrumented TPC volume. LZ will achieve a WIMP-nucleon cross section sensitivity of 1.5 x 10-48 cm2. LZ is the successor to the highly successful LUX experiment, and is being installed in the Davis Cavern water tank at the Sanford Underground Research Facility (SURF) in Lead, South Dakota.

Projected WIMP Sensitivity of the LUX-ZEPLIN (LZ) Dark Matter Experiment

Journal Article Akerib, D. - TBD

LUX-ZEPLIN (LZ) is a next generation dark matter direct detection experiment that will operate 4850 feet underground at the Sanford Underground Research Facility (SURF) in Lead, South Dakota, USA. Using a two-phase xenon detector with an active mass of 7 tonnes, LZ will search primarily for low-energy interactions with Weakly Interacting Massive Particles (WIMPs), which are hypothesized to make up the dark matter in our galactic halo. In this paper, the projected WIMP sensitivity of LZ is presented based on the latest background estimates and simulations of the detector. For a 1000 live day run using a 5.6 tonne fiducialmore »« less

First Dark Matter Search Results from the LUX-ZEPLIN (LZ) Experiment

Journal Article Aalbers, J. - TBD

The LUX-ZEPLIN (LZ) experiment is a dark matter detector centered on a dual-phase xenon time projection chamber operating at the Sanford Underground Research Facility in Lead, South Dakota, USA. This Letter reports results from LZ's first search for Weakly Interacting Massive Particles (WIMPs) with an exposure of 60 live days using a fiducial mass of 5.5 t. A profile-likelihood analysis shows the data to be consistent with a background-only hypothesis, setting new limits on spin-independent WIMP-nucleon cross-sections for WIMP masses above 9 GeV/c$^2$. The most stringent limit is set at 30 GeV/c$^2$, excluding cross sections above 5.9$$\times 10^{-48}$$ cm$^2$ atmore » the 90% confidence level.« less

The LUX-ZEPLIN (LZ) experiment

Journal Article Akerib, D.; Akerlof, C.; Akimov, D.; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

We describe the design and assembly of the LUX-ZEPLIN experiment, a direct detection search for cosmic WIMP dark matter particles. The centerpiece of the experiment is a large liquid xenon time projection chamber sensitive to low energy nuclear recoils. Rejection of backgrounds is enhanced by a Xe skin veto detector and by a liquid scintillator Outer Detector loaded with gadolinium for efficient neutron capture and tagging. LZ is located in the Davis Cavern at the 4850’ level of the Sanford Underground Research Facility in Lead, South Dakota, USA. We describe the major subsystems of the experiment and its key designmore » features and requirements.« less
