Abstract:

The SuperCDMS experiment at the Soudan Underground Laboratory is designed to detect dark matter directly by its interactions in cryogenic germanium detectors. The detectors measure particle interactions using ionization and athermal phonon signals, whose topology allows for powerful rejection of radioactive backgrounds. In this talk, I will review recent SuperCDMS results focused on light dark matter, which use multivariate analysis techniques to maximize the reach of the dataset. In light of this analysis, we are now pursuing a reanalysis using improved simulations, performing new background calibrations, and developing a novel cryogenic veto detector to suppress backgrounds in future dark matter searches. I will also discuss plans for a larger array of SuperCDMS germanium and silicon detectors to be installed in SNOLAB.
