论文摘要
我们研究了通过深色光子介质共同增强an灭灭绝的dirac暗物质候选者的现象学和检测前景。该模型逃避了早期宇宙中光热颗粒的宇宙学限制，同时又触及了当前和即将进行的陆地实验。我们对参数空间进行了全局分析，考虑了加速器和直接检测实验的界限，以及由大爆炸核合成，宇宙微波背景和暗物质自我互动引起的。我们还将讨论扩展到暗物质子分量的情况。我们发现，即使对于中等谐振剂增强的情况，也很大的参数空间区域仍然可行，并证明了不同实验策略的互补性，以进一步探索这种情况。
We study the phenomenology and detection prospects of a sub-GeV Dirac dark matter candidate with resonantly enhanced annihilations via a dark photon mediator. The model evades cosmological constraints on light thermal particles in the early universe while simultaneously being in reach of current and upcoming terrestrial experiments. We conduct a global analysis of the parameter space , considering bounds from accelerator and direct detection experiments, as well as those arising from Big Bang Nucleosynthesis, the Cosmic Microwave Background and dark matter self-interactions. We also extend our discussion to the case of a dark matter subcomponent. We find that large regions of parameter space remain viable even for the case of a moderate resonant enhancement, and demonstrate the complementarity of different experimental strategies for further exploring this scenario.
