SUMMARY:The LUX and LZ Dark Matter Experiments\, NPAC (Nuclear/Particl
 e/Astro/Cosmo) Forum\, Kevin O'Sullivan\, Yale
DESCRIPTION:Evidence from galactic rotation curves\, gravitational len
 sing\, the cosmic microwave background\, and other cosmological studie
 s point to the existence of exotic non-luminous matter\, referred to a
 s dark matter. In spite of the strong indirect evidence for the existe
 nce of dark matter\, it's composition remains unknown. One of the most
  promising putative dark matter candidates are Weakly Interacting Mass
 ive Particles (WIMPs) which would be observable through their scatters
  off ordinary matter. The Large Underground Xenon Experiment (LUX) sea
 rches for WIMPs using a large\, two-phase Xenon detector operating at 
 the Sanford Underground Research Facility (SURF). The first science ru
 n of LUX consisted of 85.3 live days with 118 kg of fiducial mass. A p
 rofile-likelihood analysis of the data shows consistency with the bac
 kground-only hypothesis\, allowing a 90% confidence limit to be set on
  the spin-independent WIMP-nucleon elastic scattering with an upper li
 mit on the cross section of 7.6x10^46 cm^2 at a WIMP mass of 33 GeV. L
 UX is continuing to take data and is working on a low-threshold analys
 is to search for light WIMPs (< 6 GeV in mass). Concurrently design wo
 rk is ongoing for the LUX-ZEPLIN (LZ) project which will be two orders
  of magnitude more sensitive than LUX.
