TL;DR: The first WIMP search data set is reported, taken during the period from April to August 2013, presenting the analysis of 85.3 live days of data, finding that the LUX data are in disagreement with low-mass W IMP signal interpretations of the results from several recent direct detection experiments.

TL;DR: This search yields no evidence of WIMP nuclear recoils and constraints on spin-independent weakly interacting massive particle (WIMP)-nucleon scattering using a 3.35×10^{4} kg day exposure of the Large Underground Xenon experiment are reported.

TL;DR: This new analysis incorporates several advances: single-photon calibration at the scintillation wavelength, improved event-reconstruction algorithms, a revised background model including events originating on the detector walls in an enlarged fiducial volume, and new calibrations from decays of an injected tritium β source and from kinematically constrained nuclear recoils down to 1.1 keV.

TL;DR: The Large Underground Xenon (LUX) detector as mentioned in this paper is a dual-phase Xenon detector with a spin independent cross-section per nucleon of 2 × 10 − 46 cm 2, equivalent to ∼ 1 event / 100 kg / month in the inner 100-kg fiducial volume (FV) of the 370-kg detector.

TL;DR: By incorporating a dilution refrigerator and Josephson parametric amplifier, this work has demonstrated total noise approaching the standard quantum limit for the first time in an axion search and reached cosmologically relevant sensitivity an order of magnitude higher in mass than any existing limits.
