Description

The EDELWEISS collaboration has performed a direct search for WIMPs using a 320g ionization-heat Ge-cryogenic detector operated in a low-background environment in the Laboratoire Souterrain de Modane. No nuclear recoils events are observed in the fiducial volume in the 30-200 keV energy range during an effective exposure of 4.53 kg.days. A limit on the cross-section of the WIMP-proton spin-independent interaction as a function of the WIMP mass is deduced. The central value of the signal reported by the DAMA experiment is excluded at 90% CL
