An Effective Field Theory Analysis of the First LUX Dark Matter Search
Akerib, D. S.; Alsum, S.; Araújo, H. M.; Bai, X.; Balajthy, J.; Baxter, A.; Bernard, E. P.; Bernstein, A.; Biesiadzinski, T. P.; Boulton, E. M.11 pages, 6 figures; The Large Underground Xenon (LUX) dark matter search was a 250-kg active mass dual-phase time projection chamber that operated by detecting light and ionization signals from particles incident on a xenon target. In December 2015, LUX reported a minimum 90% upper C.L. of 6e-46 cm^2 on the spin-independent WIMP-nucleon elastic scattering cross section based on a 1.4e4 kg*day exposure in its f...
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...

XENON
Aprile, E.; Giboni, K.-L.; Monzani, M. E.; Plante, G.; Yamashita, M.; Gaitskell, R. J.; Fiorucci, S.; Sorensen, P.; DeViveiros, L.; Bernstein, A.The XENON experiment aims at the direct detection of dark matter in the form of WIMPs (Weakly Interacting Massive Particles) via their elastic scattering off Xenon nuclei. With 1 ton of LXe distributed in ten identical modules, the proposed XENON1T experiment will achieve a sensitivity more than a factor of thousand beyond current limits.The detectors are time projection chambers operated in dual (liquid/gas) p...
