Search for MeV-scale Energy Deposits from Dark Matter in Liquid Xenon using EXO-200

Laboratory searches for dark matter typically look for nuclear recoil signals in the keV range, leaving the energy range above 1 MeV mostly unexplored. New models of dark matter that are widely compatible with astrophysical and cosmological constraints have been proposed in which the primary interactions of dark matter in detectors would produce MeV-scale energy deposits. The EXO-200 experiment, which is a 200 kg liquid xenon time projection chamber primarily focused on the search for neutrinoless double decay of Xe-136, is well suited for searching for dark matter interactions in the region between 1-10 MeV. This talk will present the expected signal topology, reconstruction and analysis for such dark matter models.
