Full Reach of CDMS-II Ge Data

ORAL

Abstract

The CDMS-II experiment was a dark matter direct-detection experiment using cryogenic ($\sim$50 mK) Si and Ge detector technologies. The original 2009 publication of results from the 2007-08 Ge data indicated 2 candidate events during a raw exposure of 612 kg-days. Since then, the raw data have been reprocessed with a post-unblinding modification to the pulse reconstruction algorithm, which improves timing for energies near threshold. I will present several analyses utilizing a full reprocessing of the CDMS-II 10 keV threshold Ge data. These include a ``standard'' CDMS analysis procedure in addition to procedures involving advanced nuclear-recoil / surface event discrimination and a likelihood approach. These analyses yield better expected sensitivities than the 2009 analysis, mostly due to improved analysis efficiencies from the improved charge reconstruction.
