“…We find that a rock density of 2.89 ± 0.06 g/cm 3 yields a total muon flux consistent with our measurement. This result agrees very well with geological studies at SURF that found an average rock density of 2.86 ± 0.11 g/cm 3 [18] (taking the nominal 4% uncertainty) based on cone 45 degrees from vertical.…”

“…The Large Underground Xenon (LUX) experiment [11] is a two-phase xenon-based dark-matter detector located at the 4850 ft level of the Sanford Underground Research Facility (SURF) [16] in Lead, South Dakota, USA. LUX was assembled and first operated in a dedicated surface facility at SURF starting in 2009.…”

The LUX experiment has performed searches for dark-matter particles scattering elastically on xenon nuclei, leading to stringent upper limits on the nuclear scattering cross sections for dark matter. Here, for results derived from 1.4 × 10 4 kg days of target exposure in 2013, details of the calibration, event-reconstruction, modeling, and statistical tests that underlie the results are presented. Detector performance is characterized, including measured efficiencies, stability of response, position resolution, and discrimination between electron-and nuclear-recoil populations. Models are developed for the drift field, optical properties, background populations, the electron-and nuclear-recoil responses, and the absolute rate of low-energy background events. Innovations in the analysis include in situ measurement of the photomultipliers' response to xenon scintillation photons, verification of fiducial mass with a low-energy internal calibration source, and new empirical models for low-energy signal yield based on large-sample, in situ calibrations.

“…[1], is a neutrinoless double-beta decay (0νββ) experiment located 4850 ft underground at the Sanford Underground Research Facility in Lead, South Dakota [2]. Majorana consists of two separate custom ultralow background modules, each containing seven arrays of P -type point contact (PPC) high-purity germanium (HPGe) detectors with a total mass of 44.1 kg, of which 29.7 kg is enriched to 88%…”

We present new limits on exotic keV-scale physics based on 478 kg d of Majorana Demonstrator commissioning data. Constraints at the 90% confidence level are derived on bosonic dark matter (DM) and solar axion couplings, Pauli exclusion principle violating (PEPV) decay, and electron decay using monoenergetic peak signal-limits above our background. Our most stringent DM constraints are set for 11.8 keV mass particles, limiting gAe < 4.5 × 10 −13 for pseudoscalars and α ′ α < 9.7 × 10 −28 for vectors. We also report a 14.4 keV solar axion coupling limit of g eff AN × gAe < 3.8 × 10 −17 , a 1 2 β 2 < 8.5 × 10 −48 limit on the strength of PEPV electron transitions, and a lower limit on the electron lifetime of τe > 1.2 × 10 24 yr for e − → invisible.PACS numbers: 95.35.+d
