The LUX experiment searches for direct evidence of galactic dark matter. Located roughly 1.5 km underground at the Sanford Underground Research Facility in Lead, South Dakota (USA), the heart of the experiment is a 370 kg liquid-xenon target, instrumented as a dual-phase (liquid/gas) time projection chamber capable of 3-D position reconstruction and nuclear recoil discrimination. The initial science results reached a record-setting sensitivity to Weakly Interacting Massive Particles (WIMPs), excluding WIMP-nucleon couplings greater than 7.6e-46 cm^2 for WIMPs of mass 33 GeV. This null result strongly rules out dark-matter interpretations of anomalous features seen in the data of several less-sensitive experiments. A versatile detector, many other dark-matter models besides WIMPs can also be probed with the same data, as is often the case with direct-detection experiments. I discuss further implications of these results, and present the current status of this on-going experiment.
