  The Large Underground Xenon (LUX) dark matter experiment is operating 1.5 km
underground at the Sanford Underground Research Facility in Lead, South Dakota,
USA. In 2013, the experiment had a WIMP search exposure of 10,091 kg-days over
a period of 85.3 live-days. This first dark matter search placed the world's
most stringent limits on WIMP-nucleon interaction cross-sections over a wide
range of WIMP masses, and is in tension with signal hints of low-mass WIMPs
from DAMA, CoGeNT and CDMS-II Si. LUX will commence a 300 day run in 2014 that
will improve the sensitivity by a factor of 5. Low-energy calibrations obtained
from a neutron double-scattering technique will further constrain and reduce
systematics, particularly for low WIMP masses.
