EDELWEISS dark matter search: Latest results and future plans
نویسنده
چکیده
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.

Latest Results of the Edelweiss Experiment
The Edelweiss experiment is a direct detection Dark Matter Search, under the form of WIMPs. It uses heat and ionization Ge cryogenic detectors.We present the latest results obtained by the experiment with three new 320 g bolometers. At present, Edelweiss I is the most sensitive experiment for all WIMP masses compatible with accelerator constraints (M W IM P > 30 GeV).We also briefly describe th...
متن کاملEDELWEISS - 2 Dark Matter Search : recent results with new detectors
EDELWEISS-2 is a direct dark matter (DM) search experiment using cryogenic Germanium bolometers. The most promising DM candidate, a so-called weakly interacting massive particle, WIMP, is expected to scatter off the target nuclei thus depositing a tiny energy in the detectors. A powerful event selection and good background knowledge are of crucial importance in this case. The experiment is situ...

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 equipped with interleaved electrodes for the rejection of surface events. Limits on the elastic and inelastic cross-sections of spin-independent interactions of WI...
متن کاملDirect and Indirect Detection of Wimps
We present here the principles of detection of Weakly Interacting Massive Particles , which could represent a large contribution to Dark Matter. A status of the experimental situation is given both for indirect and direct detection. In particular , the DAMA claim for a WIMP signal is confronted to the recent results of the CDMS and EDELWEISS experiments. We conclude by comparing direct and indi...
متن کاملLycen-2009-07 Direct Dark Matter Searches and the Edelweiss-ii Experiment
Direct searches for Dark Matter are experiment dedicated to the observation of the energetic recoiling ions produced by the scattering of WIMP particles from our galactic halo on terrestrial targets. The status and prospects of some currently running experiments are presented, together with new preliminary results of the experiments EDELWEISS-II.
