First Science Results from the LUX Dark Matter Experiment

ABSTRACT
The LUX (Large Underground Xenon) experiment is designed for the direct 
detection of dark matter particles via their collisions with xenon 
nuclei. This two-phase xenon time-projection chamber, operating at the 
Sanford Underground Research Facility (Lead, South Dakota), was cooled 
and filled in February 2013. Results will be presented from the first 
dark matter search data set, taken during the period April to August 
2013 and corresponding to 85.3 live-days of data with a fiducial mass of 
118 kg. The experiment exhibited a sensitivity to spin-independent 
WIMP-nucleon elastic scattering with a minimum upper limit on the cross 
section of 7.6 x 10^-46 cm^2 at a WIMP mass of 33 GeV/c^2. The LUX 
results are inconsistent with the low-mass WIMP signal interpretations 
of data from several recent direct detection experiments. This talk will 
provide an overview of the LUX experiment, focusing on the recent 
science results.
