论文摘要
我们考虑搜索由低质量暗物质的an灭或腐烂产生的伽玛射线，这些暗物质与夸克伴侣。在这种情况下，大多数光子都是从$π^0 $或$η$ erson的衰减中产生的。由于介子质量的差异，这些衰变会产生明显不同的光子特征。我们评估了未来的MEV范围观测值的能力，以限制暗物质an灭或衰减所产生的光子光谱所产生的HADRONIC最终状态。然后，我们根据低能量QCD的近似对称性来评论如何使用此信息来确定暗物质耦合到夸克电流的性质。
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 $π^0$ or $η$ mesons. These decays produce distinctly different photon signatures due to the difference in meson mass. We assess the ability of the future MeV-range observatories to constrain the hadronic final states produced by dark matter annihilation or decay from the shape of the resulting photon spectrum. We then comment on how this information can be used to determine properties of the dark matter coupling to the quark current, based on the approximate symmetries of low-energy QCD.
