Search for New Physics via Low-Energy Electron Recoils with a 4.2 Tonne\times Year Exposure from the LZ Experiment

D. S. Akerib, A. K. Al Musalhi, F. Alder, J.O. Almquist et autres

We report results from searches for new physics models through electron recoils using data collected by the LUX-ZEPLIN (LZ) experiment during its first two science runs, with a total exposure of 4.2 tonne-years. The observed data are consistent with a background-only hypothesis. …

The XLZD Design Book: towards the next-generation liquid xenon observatory for dark matter and neutrino physics

J. Aalbers, K. Abe, Miquel Adrover, S. Ahmed Maouloud et autres

Abstract This report describes the experimental strategy and technologies for XLZD, the next-generation xenon observatory sensitive to dark matter and neutrino physics. In the baseline design, the detector will have an active liquid xenon target of 60 tonnes, which could be increased …

New Constraints on Cosmic Ray-Boosted Dark Matter from the LUX-ZEPLIN Experiment

D. S. Akerib, A. K. Al Musalhi, F. Alder, C. S. Amarasinghe et autres

While dual-phase xenon time projection chambers have driven the sensitivity toward weakly interacting massive particles at the GeV/c^{2} to TeV/c^{2} mass scale, the scope for sub-GeV/c^{2} dark matter particles is hindered by a limited nuclear recoil energy detection threshold. One approach to …

First Constraint on Atmospheric Millicharged Particles with the LUX-ZEPLIN Experiment

J. Aalbers, D. S. Akerib, A. K. Al Musalhi, F. Alder et autres

We report on a search for millicharged particles (mCPs) produced in cosmic ray atmospheric interactions using data collected during the first science run of the LUX-ZEPLIN experiment. The mCPs produced by two processes-meson decay and proton bremsstrahlung-are considered in this study. This …

Dark Matter Search Results from 4.2 Tonne − Years of Exposure of the LUX-ZEPLIN (LZ) Experiment

D. S. Akerib, A. K. Al Musalhi, F. Alder, C. S. Amarasinghe et autres

We report results of a search for nuclear recoils induced by weakly interacting massive particle (WIMP) dark matter using the LUX-ZEPLIN (LZ) two-phase xenon time projection chamber. This analysis uses a total exposure of 4.2±0.1 tonne-years from 280 live days of LZ …

Two-neutrino double electron capture of 124 Xe in the first LUX-ZEPLIN exposure

J. Aalbers, D. S. Akerib, A. K. Al Musalhi, F. Alder et autres

Abstract The broad physics reach of the LUX-ZEPLIN (LZ) experiment covers rare phenomena beyond the direct detection of dark matter. We report precise measurements of the extremely rare decay of 124 Xe through the process of two-neutrino double electron capture, utilizing a …

We report results of a search for nuclear recoils induced by weakly interacting massive particle (WIMP) dark matter using the LUX-ZEPLIN (LZ) two-phase xenon time projection chamber. This analysis uses a total exposure of $4.2\pm0.1$ tonne-years from 280 live days of LZ …

The design, implementation, and performance of the LZ calibration systems

J. Aalbers, D. S. Akerib, A. K. Al Musalhi, F. Alder et autres

Abstract LUX-ZEPLIN (LZ) is a tonne-scale experiment searching for direct dark matter interactions and other rare events. It is located at the Sanford Underground Research Facility (SURF) in Lead, South Dakota, USA. The core of the LZ detector is a dual-phase xenon …

New constraints on ultraheavy dark matter from the LZ experiment

J. Aalbers, D. S. Akerib, A. K. Al Musalhi, C. S. Amarasinghe et autres

Searches for dark matter with liquid xenon time projection chamber experiments have traditionally focused on the region of the parameter space that is characteristic of weakly interacting massive particles, ranging from a few GeV / c 2 to a few TeV / …
