Exclusion limits on the WIMP-nucleon cross section from the cryogenic dark matter search.

چکیده
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 GeV/c2 WIMP mass and, at >75% C.L., the entire 3sigma allowed region for the WIMP signal reported by the DAMA experiment.

متن کاملA Search for Dark Matter Using Cryogenic Detectors (cdms)
The Cryogenic Dark Matter Search experiment uses germanium and silicon detectors cooled to cryogenic temperatures in a direct search for weakly-interacting massive particles in our Galaxy. The novel detectors allow a high degree of background rejection by discriminating between electron and nuclear recoils through the simultaneous measurement of the energy deposited in phonons (heat) and ioniza...
