Abstract

The EDELWEISS-II collaboration has completed a direct search for WIMP dark matter with an array of ten 400g cryogenic germanium detectors allowing simultaneous measurement of heat and ionisation in operation at the Laboratoire Souterrain de Modane. A total e ective exposure of 384 kg*d has been achieved, mostly coming from fourteen months of continuous operation. Five nuclear recoil candidates are observed above 20 keV, while the estimated background is less than 3 events. The result is interpreted in terms of limits on the cross-section of spin-independent interactions of WIMPs and nucleons. New constraints are also set on inelastic WIMP-nucleon models.
