Results from a Search for Dark Matter in the Complete LUX Exposure.

We report constraints on spin-independent weakly interacting massive particle (WIMP)-nucleon scattering using a 3.3510^{4}kgday exposure of the Large Underground Xenon (LUX) experiment. A dual-phase xenon time projection chamber with 250kg of active mass is operated at the Sanford Underground Research Facility under Lead, South Dakota (USA). With roughly fourfold improvement in sensitivity for high WIMP masses relative to our previous results, this search yields no evidence of WIMP nuclear recoils. At a WIMP mass of 50GeVc^{-2}, WIMP-nucleon spin-independent cross sections above 2.210^{-46}cm^{2} are excluded at the 90% confidence level. When combined with the previously reported LUX exposure, this exclusion strengthens to 1.110^{-46}cm^{2} at 50GeVc^{-2}.
