TLDR
Lux-ZEPLIN (LZ) as mentioned in this paper 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.
Abstract
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 56-tonne fiducial mass, LZ is projected to exclude at 90% confidence level spin-independent WIMP-nucleon cross sections above 14 × 10-48cm2 for a 40 GeV/c2 mass WIMP Additionally, a 5σ discovery potential is projected, reaching cross sections below the exclusion limits of recent experiments For spin-dependent WIMP-neutron(-proton) scattering, a sensitivity of 23 × 10−43 cm2 (71 × 10−42 cm2) for a 40 GeV/c2 mass WIMP is expected With underground installation well underway, LZ is on track for commissioning at SURF in 2020
