Abstract
Cryogenic Dark Matter Search (CDMS) employs Ge and Si detectors to search f or weakly interacting massive particles (WIMPs) via their elastic-scatterin g interactions with nuclei while discriminating against interactions of bac kground particles. CDMS data, accounting for the neutron background, give l imits on the spin-independent WIMP-nucleon elastic-scattering cross section that exclude unexplored parameter space above 10 GeV/c(2) WIMP mass and, a t >75% C.L., the entire 3 sigma allowed region for the WIMP signal reported by the DAMA experiment.
