Abstract

We present constraints on low-mass dark matter electron scattering and absorption interactions using a SuperCDMS high-voltage eV-resolution (HVeV) detector. Data were taken underground in the NEXUS facility located at Fermilab with an overburden of 225 meters of water equivalent. The experiment benefits from the minimizing of luminescence from the printed circuit boards in the detector holder used in all previous HVeV studies. A blind analysis of 6.1 g·days of exposure produces exclusion limits for dark matter-electron scattering cross sections for masses as low as 1 MeV/c2, as well as on the photon-dark photon mixing parameter and the coupling constant between axionlike particles and electrons for particles with masses?> 1.2 eV/c2 probed via absorption processes.
