Presentation Dark Matter Direct Detection Dark Matter: Direct Detection


Alexandre Lindote (L)


The LUX dark matter search experiment, the world's largest dual-phase xenon time projection chamber, is installed 1478 m underground at the Sanford Underground Research Facility in Lead, SD, USA. In this talk I will present the results from the first WIMP search run of LUX: from a total exposure of 85 live-days, we found no evidence of signal above expected background, constraining the spin-independent WIMP-nucleon scattering cross section above 7.6x10^-46 cm^2 at 33 GeV/c^2 WIMP mass (90% C.L.) - three times more sensitive than any competing experiment. The improvement in sensitivity is more significant at low energies, and is in conflict with low-mass WIMP signal interpretations of other results.
