Search for Low-Mass Weakly Interacting Massive Particles with SuperCDMS

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/c[superscript 2], with the signal region blinded. Eleven events were observed after unblinding....

Description
Summary: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/c[superscript 2], 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 1.2 × 10[superscript −42]  cm[superscript 2] at 8  GeV/c[superscript 2]. 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/c[superscript 2].
