Abstract:

Abstract: The DAMIC experiment exploits the exceptional energy and spatial resolution of charge coupled devices (CCDs) to search for dark matter particles. We present the latest results from the 13 kg-day exposure collected with the DAMIC detector at SNOLAB. We build on previous analyses
to distinguish between bulk and surface backgrounds to construct a robust radioactive background model down to energies as low as 50 eVee. We compare the observed spectrum of events to the background-model prediction to search for an excess bulk signal, as would be expected from dark matter.
