Dark matter search results from DAMIC

Abstract

We present the current status of DAMIC at SNOLAB: A search for low-mass dark matter (DM) particles with low-noise CCDs. A 40 g 7-CCD array started operation in February 2017 and DM search data was acquired throughout 2017{2019. We summarize recent results on the search for few-e- ionization signals induced by electronic recoils from the scattering of DM particles with masses ∼MeVc-2 or the absorption of hidden photons with masses 1{10 eV c-2. We report on the status of the search for ionization signals greater than 15 e- from recoiling silicon nuclei following the scattering of DM particles with masses ∼GeV c-2.
