We report a first search for weakly interacting massive particles (WIMPs) using the background rejection capabilities of SuperCDMS. An exposure 577 kg days was analyzed WIMPs with mass <30 GeV/c(2), signal region blinded. Eleven events were observed after unblinding. set an upper limit on spin-independent WIMP-nucleon cross section 1.2×10(-42) cm(2) at 8 GeV/c(2). This result is in tension WIMP interpretations recent experiments and probes new parameter space scattering masses <6
The SuperCDMS experiment is designed to directly detect weakly interacting massive particles (WIMPs) that may constitute the dark matter in our Galaxy. During its operation at Soudan Underground Laboratory, germanium detectors were run CDMSlite mode gather data sets with sensitivity specifically for WIMPs masses ${<}$10 GeV/$c^2$. In this mode, a higher detector-bias voltage applied amplify phonon signals produced by drifting charges. This paper presents studies of experimental noise and...

We report the result of a blinded search for Weakly Interacting Massive Particles (WIMPs) using majority SuperCDMS Soudan dataset. With an exposure 1690 kg days, single candidate event is observed, consistent with expected backgrounds. This analysis (combined previous Ge results) sets upper limit on spin-independent WIMP--nucleon cross section $1.4 \times 10^{-44}$ ($1.0 10^{-44}$) cm$^2$ at 46 GeV/$c^2$. These results set strongest limits WIMP--germanium-nucleus interactions masses $>$12

Scattering-induced energy loss is calculated two stages: virtuality stage based matter model, which scattering highly virtual partons modifies vacuum radiation pattern, second at lower lbt leading gain...

The SuperCDMS experiment in the Soudan Underground Laboratory searches for dark matter with a 9-kg array of cryogenic germanium detectors. Symmetric sensors on opposite sides measure both charge and phonons from each particle interaction, providing excellent discrimination between electron nuclear recoils, surface interior events. Surface event rejection capabilities were tested two 210Pb sources producing ∼130 beta decays/hr. In ∼800 live hours, no events leaked into 8–115 keV signal...

We measured the nuclear-recoil ionization yield in silicon with a cryogenic phonon-sensitive gram-scale detector. Neutrons from monoenergetic beam scatter off of nuclei at angles corresponding to energy depositions 4 keV down 100 eV, lowest probed so far. The results show no sign an production threshold above eV. These call for further investigation theory and comprehensive determination detector response function energies below scale.

Recent experiments searching for $\mathrm{sub}\text{\ensuremath{-}}\mathrm{GeV}/{c}^{2}$ dark matter have observed event excesses close to their respective energy thresholds. Although specific the individual technologies, measured excess rates been consistently reported at or below energies of a few-hundred eV, with charges few electron-hole pairs. In present work, we operated 1-g silicon SuperCDMS-HVeV detector three voltages across crystal (0, 60 and 100 V). The 0 V data show an events in...
