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

The Cryogenic Dark Matter Search (CDMS) aims to detect WIMPs in the galactic halo by observation of elastic scattering interactions with nuclei in germanium and silicon targets. CDMS uses novel cryogenic detectors that actively reject typical radioactive backgrounds, and thus is ultimately vastly more sensitive to WIMP interactions than previous experiments. We present limits on the WIMP-nucleon elastic scattering cross section based on data acquired during recent runs, reflecting significant detector and background improvements.
