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 WIMPs via their elastic-scattering interactions with nuclei while discriminating against interactions of background particles. CDMS I data, from the Stanford Underground Facility shallow site, give limits on the spin-independent WIMPnucleon elastic-scattering cross-section that exclude unexplored parameter space a...

Exclusion Limits on the WIMP-Nucleon Elastic-Scattering Cross Section from the Cryogenic Dark Matter Search by Sunil Ramanlal Golwala Doctor of Philosophy in Physics University of California at Berkeley Professor Bernard Sadoulet, Chair Extensive evidence indicates that a large fraction of the matter in the universe is nonluminous, nonbaryonic, and “cold” — nonrelativistic at the time matter be...
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...
متن کاملResults and Status of the Cryogenic Dark Matter Search ( CDMS )
The Cryogenic Dark Matter Search experiment uses cooled germanium and silicon detectors for 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 and ionization. Exposures on the order of ...
متن کاملResults from the Cryogenic Dark Matter Search at Soudan Underground Laboratory
We present results from the Cryogenic Dark Matter Search at Soudan Underground Laboratory for two-tower arrays of detector. Twelve detectors were operated from March 25 to August 8, 2004, or 74.5 detector live days. Within expected background, no statistically significant indication of a WIMP signal was observed. Based on this null observation and combined with our previous results, we exclude ...
