论文摘要
我们对具有GEV规模的暗物质与Baryons和Lepton的模型进行系统分析。这些理论提供了一个自然框架来解释宇宙的物质抗对称性。我们发现，只有少数重的baryonic暗物质模型没有树级质子衰减，而无需明确施加重生子数字。我们列举了这些案件，并简要概述了它们的现象学。然后，我们专注于一个麻血的暗物质模型，以更详细地讨论通过瘦肉生成，黑暗扇区中的对称性恢复以及间接检测实验中预期的暗物质歼灭信号。
We perform a systematic analysis of models with GeV-scale dark matter coupled to baryons and leptons. Such theories provide a natural framework to explain the matter-antimatter asymmetry of the universe. We find that only a few baryonic dark matter models are free from tree-level proton decay without explicitly imposing baryon number conservation. We enumerate those cases and provide a brief overview of their phenomenology. We then focus on a leptonic dark matter model for a more detailed discussion of the baryon asymmetry generation via leptogenesis, the symmetry restoration in the dark sector and the expected dark matter annihilation signals in indirect detection experiments.
