SuperCDMS SNOLAB will be a next-generation experiment aimed at directly detecting low-mass (< 10 GeV/c$^2$) particles that may constitute dark matter by using cryogenic detectors of two types (HV and iZIP) target materials (germanium silicon). The is being designed with an initial sensitivity to nuclear recoil cross sections ~ 1 x 10$^{-43}$ cm$^2$ for particle mass GeV/c$^2$, capacity continue exploration both smaller masses better sensitivities. phonon the HV sufficient detect recoils from...
We present the first limits on inelastic electron-scattering dark matter and photon absorption using a prototype SuperCDMS detector having charge resolution of 0.1 electron-hole pairs (CDMS HVeV, 0.93 g CDMS high-voltage device). These electron-recoil significantly improve experimental constraints particles with masses as low 1 MeV/c^{2}. demonstrate sensitivity to photons competitive other leading approaches but substantially less exposure (0.49 d). results scientific potential...
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...
This article presents an analysis and the resulting limits on light dark matter inelastically scattering off of electrons, photon axion-like particle absorption, using a second-generation SuperCDMS high-voltage eV-resolution detector. The 0.93 gram Si detector achieved 3 eV phonon energy resolution; for bias 100 V, this corresponds to charge resolution 3% single electron-hole pair. spectrum is reported from blind with 1.2 gram-days exposure acquired in above-ground laboratory. With carrier...

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

We present an analysis of electron recoils in cryogenic germanium detectors operated during the SuperCDMS Soudan experiment. The data are used to set new constraints on axioelectric coupling axionlike particles and kinetic mixing parameter dark photons, assuming respective species constitutes all galactic matter. This study covers mass range from $40\text{ }\text{ }\mathrm{eV}/{c}^{2}$ $500\text{ }\mathrm{keV}/{c}^{2}$ for both candidates, excluding previously untested space masses below...
We present a new analysis of previously published SuperCDMS data using profile likelihood framework to search for sub-GeV dark matter (DM) particles through two inelastic scattering channels: bremsstrahlung radiation and the Migdal effect. By considering these possible channels, experimental sensitivity can be extended DM masses that are undetectable DM-nucleon elastic channel, given energy threshold current experiments. exclude down $220~\textrm{MeV}/c^2$ at $2.7 \times...
