abstract
We report a first search for weakly interacting massive particles (WIMPs) using the background rejection capabilities of SuperCDMS. An exposure of 577 kg-days was analyzed for WIMPs with mass < 30 GeV/c2, with the signal region blinded. Eleven events were observed after unblinding. We set an upper limit on the spin-independent WIMP-nucleon cross section of 1.2e-42 cm2 at 8 GeV/c2. This result is in tension with WIMP interpretations of recent experiments and probes new parameter space for WIMP-nucleon scattering for WIMP masses < 6 GeV/c2.

Supernova cooling from neutrino-devouring dark matter
Supernova cooling excludes fermionic dark matter produced by neutrino scattering down to cross sections of about 10^-58 cm^2 for electrons and 10^-56 cm^2 for nucleons across the keV to 100 MeV mass range.
