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 two-phase xenon detector with an active mass of 7 tonnes, LZ search primarily for low-energy interactions weakly interacting massive particles (WIMPs), which are hypothesized to make up our galactic halo. In this paper, projected WIMP sensitivity presented based on latest background estimates...
The LUX-ZEPLIN (LZ) experiment is a dark matter detector centered on dual-phase xenon time projection chamber. We report searches for new physics appearing through few-keV-scale electron recoils, using the experiment's first exposure of 60 live days and fiducial mass 5.5 t. data are found to be consistent with background-only hypothesis, limits set models including solar axion coupling, neutrino magnetic moment millicharge, couplings galactic axionlike particles hidden photons.

Dual-phase xenon detectors, as currently used in direct detection dark matter experiments, have observed elevated rates of background electron events the low energy region. While this negatively impacts detector performance various ways, its origins only been partially studied. In paper we report a systematic investigation pathologies LUX experiment. We characterize different populations based on their emission intensities and correlations with preceding depositions detector. By studying...
The LUX-ZEPLIN experiment recently reported limits on WIMP-nucleus interactions from its initial science run, down to $6.5\times10^{-48}$ cm$^2$ for the spin-independent interaction of a 30 GeV/c$^2$ WIMP at 90% confidence level.

Dual-phase xenon time projection chamber (TPC) detectors offer heightened sensitivities for dark matter detection across a spectrum of particle masses. To broaden their capability to low-mass interactions, we investigated the light and charge responses liquid (LXe) sub-keV nuclear recoils. Using neutron events from pulsed Adelphi Deuterium-Deuterium generator, an in situ calibration was conducted on LUX detector. We demonstrate direct measurements yields down 0.45 0.27 keV, respectively,...

Surrounding TPC, two veto detectors immersed an ultra-pure water tank enable...
Abstract Weakly interacting massive particles (WIMPs) may interact with a virtual pion that is exchanged between nucleons.

We observe no significant excess and set an upper limit 1.5 × 10 −46 cm 2 at...
The first science run of the LUX-ZEPLIN (LZ) experiment, a dual-phase xenon time project chamber operating in Sanford Underground Research Facility South Dakota, USA, has reported leading limits on spin-independent WIMP-nucleon interactions and described from non-relativistic effective field theory (NREFT).
