EDELWEISS dark matter search: Latest results and future plans

Abstract : EDELWEISS is a direct search for WIMP dark matter using cryogenic heat-and-ionization germanium detectors. We report the final results of the second stage of the experiment, EDELWEISS-II, obtained with an array of ten 400 g detectors. A total effective exposure of 384 kg.day has been achieved, obtained following fourteen months of continuous operation at the Laboratoire Souterrain de Modane. Five nuclear recoil candidates are observed above 20 keV, while the estimated background is less than 3 events. We also present the prospects of EDELWEISS-III, which plans to accumulate more than 3000 kg.day of data with fourty new 800 g detectors.
