  The SuperCDMS experiment searches for weakly interacting massive particles
(WIMPs) using cryogenic germanium detectors that measure ionization and phonon
energy. Several direct searches for WIMPs have recently reported excesses of
events above their background expectations, which could be interpreted as WIMPs
with masses in the 8-20 GeV/c^2 range. The excellent intrinsic signal-to-noise
of SuperCDMS detectors and their powerful background rejection make SuperCDMS
an ideal experiment to further test these signal hints. We present the results
of two recent SuperCDMS analyses targeting this mass range: the first using
Luke-Neganov amplification of the ionization signal to lower the effective
energy threshold, and the second using multivariate methods to optimize
background rejection in a larger 577 kg-d exposure.
