Agnese, R. et al., First Dark Matter Constrains from a SuperCDMS Single-Charge Sensitive Detector. Phys. Rev. Lett. 121, 051301 , erratum : Phys. Rev. Lett. 122, 069901 .

Public Material: HVeV Run1: Updated DM-Electron Scattering Cross Section Limits

We present the first limits on inelastic electron-scattering dark matter and dark photon absorption using a prototype SuperCDMS detector having a charge resolution of 0.1 electron-hole pairs (CDMS HVeV, a 0.93 gram CDMS HV device). These electron-recoil limits significantly improve experimental constraints on dark matter particles with masses as low as 1 MeV/c2. We demonstrate a sensitivity to dark photons competitive with other leading approaches but using substantially less exposure (0.49 gram days). These results demonstrate the scientific potential of phonon-mediated semiconductor detectors that are sensitive to single electronic excitations.
