Abstract

The Large Underground Xenon experiment is searching for interactions of galactic dark matter particles in a 250 kg liquid xenon target. LUX features a double-phase xenon TPC, and operates at the 4850-ft level of the Sanford Underground Research Facility, South Dakota. Results from 2013 put new constraints on the elastic scattering of WIMPs off nucleons. A very low energy threshold for nuclear recoil detection and novel calibration techniques have allowed a 20-fold improvement in sensitivity relative to previous experiments. LUX's null result can only be reconciled with controversial signal claims under the most contrived set of assumptions. I will also discuss the prospects for the longer science run in 2014.
