First Dark Matter Search Results from the LUX-ZEPLIN (LZ) Experiment
Aalbers, J.; Akerib, D. S.; Akerlof, C. W.; Al Musalhi, A. K.; Alder, F.; Alqahtani, A.; Alsum, S. K.; Amarasinghe, C. S.; Ames, A.; Anderson, T. J.9 pages, 8 figures. See https://doi.org/10.1103/PhysRevLett.131.041002 for a data release related to this paper; The LUX-ZEPLIN experiment is a dark matter detector centered on a dual-phase xenon time projection chamber operating at the Sanford Underground Research Facility in Lead, South Dakota, USA. This Letter reports results from LUX-ZEPLIN's first search for weakly interacting massive particles (WIMPs) wit...
The LUX-ZEPLIN (LZ) radioactivity and cleanliness control programs
Akerib, D. S.; Akerlof, C. W.; Akimov, D. Yu.; Alquahtani, A.; Alsum, S. K.; Anderson, T. J.; Angelides, N.; Araújo, H. M.; Arbuckle, A.LUX-ZEPLIN (LZ) is a second-generation direct dark matter experiment with spin-independent WIMPnucleon scattering sensitivity above 1.4 × 10−48 cm2 for a WIMP mass of 40 GeV/c2 and a 1000 days exposure. LZ achieves this sensitivity through a combination of a large 5.6 t fiducial volume, active inner and outer veto systems, and radio-pure construction using materials with inherently low radioactivity content. Th...

Radiogenic and muon-induced backgrounds in the LUX dark matter detector
Akerib, D. S.; Araújo, H. M.; Bai, X.; Bailey, A. J.; Balajthy, J.; Bernard, E.; Bernstein, A.; Bradley, A.; Byram, D.; Cahn, S. B.The Large Underground Xenon (LUX) dark matter experiment aims to detect rare low-energy interactions from Weakly Interacting Massive Particles (WIMPs). The radiogenic backgrounds in the LUX detector have been measured and compared with Monte Carlo simulation. Measurements of LUX high-energy data have provided direct constraints on all background sources contributing to the background model. The expected backgro...
