Commissioning and first results from the Cold Radon Emanation Facility
Emily Perry, Chamkaur Ghag, Maurits Van der Grinten +4
Radon emanation from detector materials is a critical background for next-generation rare event searches, in particular those using noble liquid targets. While highly sensitive scr…
The 20 GeV Galactic Halo Excess: Pixel-Level Confirmation and Consistency with Sub-TeV WIMP Annihilation
Trinity Rosebud Stenhouse, Chamkaur Ghag, Frank F. Deppisch
A recent analysis of 15 years of Fermi-LAT data reported a spherically symmetric, halo-like component of the Galactic diffuse emission that peaks near 20GeV. We independently repro…
Precision measurement of positron decay modes of Xe-125 in the LUX-ZEPLIN experiment
D. S. Akerib, A. K. Al Musalhi, F. Alder +208
The radioisotope is a short-lived () activation product of the neutron calibrations performed in the LUX-ZEPLIN experiment. Subsequently, $^{12…
Pushing the Limits of Pulse Shape Discrimination in a Large Liquid Xenon Detector
D. S. Akerib, A. K. Al Musalhi, F. Alder +213
The LUX-ZEPLIN (LZ) experiment is a direct-detection dark matter experiment, optimized to search for weakly interacting massive particles (WIMPs) through WIMP-nucleon interactions.…
Study of few-electron backgrounds in the LUX-ZEPLIN detector
D. S. Akerib, A. K. Al Musalhi, F. Alder +204
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/--Te…
Low-Energy Radon Backgrounds from Electrode Grids in Dual-Phase Xenon TPCs
D. S. Akerib, A. K. Al Musalhi, F. Alder +264
The dual-phase xenon time projection chamber (TPC) is a powerful technology to detect rare interactions such as scatters of dark matter particles on nuclei. In particular, the buil…
