Minding the MeV Gap: the Indirect Detection of Low Mass Dark Matter
  We consider the prospects for the indirect detection of low mass dark matter
which couples dominantly to quarks. If the center of mass energy is below about
280 MeV, the kinematically allowed final states will be dominated by photons
and neutral pions, producing striking signatures at gamma ray telescopes. In
fact, an array of new instruments have been proposed, which would greatly
improve sensitivity to photons in this energy range. We find that planned
instruments can improve on current sensitivity to dark matter models of this
type by up to a few orders of magnitude.
