Silicon detector results from the first five-tower run of CDMS II

# abstract
We report results of a search for weakly interacting massive particles (WIMPs) with the Si detectors of the CDMS II experiment. This report describes a blind analysis of the first data taken with CDMS IIs full complement of detectors in 20062007; results from this exposure using the Ge detectors have already been presented. We observed no candidate WIMP-scattering events in an exposure of 55.9 kg-days before analysis cuts, with an expected background of 1.1 events. The exposure of this analysis is equivalent to 10.3 kg-days over a recoil energy range of 7100 keV for an ideal Si detector and a WIMP mass of 10 GeV/c2. These data set an upper limit of 1.710-41 cm2 on the WIMP-nucleon spin-independent cross section of a 10 GeV/c2 WIMP. These data exclude parameter space for spin-independent WIMP-nucleon elastic scattering that is relevant to recent searches for low-mass WIMPs.
