Exclusion Limits on the WIMP-Nucleon Cross Section from the Cryogenic Dark Matter Search

The Cryogenic Dark Matter Search (CDMS) employs Ge and Si detectors to search for weakly interacting massive particles (WIMPs) via their elastic-scattering interactions with nuclei while discriminating against interactions of background particles. CDMS data, accounting for the neutron background, give limits on the spin-independent WIMP-nucleon elastic-scattering cross section that exclude unexplored parameter space above $10\mathrm{GeV}/c^2$ WIMP mass and, at $>75\mathrm{}\%$ C.L., the entire $3\sigma$ allowed region for the WIMP signal reported by the DAMA experiment.
