We consider the search for gamma rays produced by the annihilation or decay of low-mass dark matter which couples to quarks. In this scenario, most of the photons are produced from the decays of ${\ensuremath{\pi}}^{0}$ or $\ensuremath{\eta}$ mesons. These decays produce distinctly different photon signatures due to the difference in …
