Study of few-electron backgrounds in the LUX-ZEPLIN detector

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

The LUX-ZEPLIN (LZ) experiment aims to detect rare interactions between dark matter particles and xenon. Although the detector is designed to be the most sensitive to GeV/$c^2$--TeV/$c^2$ Weakly Interacting Massive Particles (WIMPs), it is also capable of measuring low-energy ionization signals down …

Low-energy nuclear recoil calibration of the LUX-ZEPLIN experiment with a photoneutron source

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

The LZ experiment is a liquid xenon time-projection chamber (TPC) searching for evidence of particle dark matter interactions. In the simplest assumption of elastic scattering, many dark matter models predict an energy spectrum which rises quasi-exponentially with decreasing energy transfer to a …

Measurements and models of enhanced recombination following inner-shell vacancies in liquid xenon

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

Electron-capture decays of Xe 125 and Xe 127 , and double-electron-capture decays of Xe 124 , are backgrounds in searches for weakly interacting massive particles (WIMPs) conducted by dual-phase xenon time projection chambers such as LUX-ZEPLIN (LZ). These decays produce signals with …

First constraint for atmospheric millicharged particles with the LUX-ZEPLIN experiment

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

We report on a search for millicharged particles (mCPs) produced in cosmic ray proton 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 …

Probing the Scalar WIMP-Pion Coupling with the first LUX-ZEPLIN data

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

Weakly interacting massive particles (WIMPs) may interact with a virtual pion that is exchanged between nucleons. This interaction channel is important to consider in models where the spin-independent isoscalar channel is suppressed. Using data from the first science run of the LUX-ZEPLIN …

The Data Acquisition System of the LZ Dark Matter Detector: FADR

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

The Data Acquisition System (DAQ) for the LUX-ZEPLIN (LZ) dark matter detector is described. The signals from 745 PMTs, distributed across three subsystems, are sampled with 100-MHz 32-channel digitizers (DDC-32s). A basic waveform analysis is carried out on the on-board Field Programmable …

A next-generation liquid xenon observatory for dark matter and neutrino physics

S. Ahmed Maouloud, Fiona Alder, A. Ames, Bernard Andrieu et autres

The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leading technology to cover the available parameter space for weakly interacting massive particles, while featuring extensive …
