| Abstract: | Weakly Interacting Massive Particles (WIMPs) are a class of yet to be discovered particles hypothesized to be components of the non-baryonic dark matter content of the universe. By operating cryogenic semiconductor Ge/Si detectors, the CDMS collaboration identifies WIMP nucleus scattering events as such by measuring the induced ionization and athermal phonon energies. This talk will describe the recent CDMSII-Si results from a blind analysis of 140 kg-days of exposure that presented 3 WIMP-candidate events with an expected total background of 0.7 events. I will also discuss the measured performance of the new iZIP detectors installed in the Soudan mine and taking Dark Matter search data since march 2012. Moreover, I will present the new CDMSLite result which is a modified configuration of iZIP detectors that resulted in a world leading exclusion limit on low mass WIMPs. Eventually, I will present recent works about the expected neutrino background to direct Dark Matter searches that places a lower limit on the WIMP-nucleon cross section achievable by upcoming ton-scale experiments. | |
