Search for new physics in low-energy electron recoils from the first LZ exposure
Aalbers, J.; Akerib, D. S.; Al Musalhi, A. K.; Alder, F.; Amarasinghe, C. S.; Ames, A.; Anderson, T. J.; Angelides, N.; Araújo, H. M.; Armstrong, J. E.The LUX-ZEPLIN (LZ) experiment is a dark matter detector centered on a dual-phase xenon time projection chamber. We report searches for new physics appearing through few-keV-scale electron recoils, using the experiment’s first exposure of 60 live days and a fiducial mass of 5.5 t. The data are found to be consistent with a background-only hypothesis, and limits are set on models for new physics including solar ...

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...
To advance sustainable stewardship, we must document not only biodiversity but ...
Schrodt, F.; Bailey, J.; Kissling, W. D.; Rijsdijk, K. F.; Seijmonsbergen, A. C.; Ree, D.; Hjort, J.; Lawley, R. S.; Williams C. N.; Anderson, M. G.Rapid environmental change is driving the need for complex and comprehensive scientific information that supports policies aimed at managing natural resources through international treaties, platforms, and networks. One successful approach for delivering such information has been the development of essential variables for climate, oceans, biodiversity, and sustainable development goals. Although the current ess...
