Event description: 

The identification of dark matter has become one of the most fundamental challenges in modern cosmology. Weakly Interacting Massive Particles (WIMPs) are one of the leading candidates for the undetected mass component comprising approximately 27% of the observable universe. Using high-purity germanium detectors instrumented with ionization and phonon sensors and operated at cryogenic temperatures, the Cryogenic Dark Matter Search (CDMS) experiment looks for WIMP dark matter candidates by searching for an excess and annual modulation in the detected rate of nuclear recoil events in the detector. Building upon the initial search for annual modulation in CDMS II, I will discuss the recent improvements to the application of background subtraction in the modulation analysis.
