标题： Dark Matter Annihilation inside Large Volume Neutrino Detectors

摘要： 超出标准模型的新粒子可以表现为与可见物质强烈相互作用且构成总暗物质丰度一小部分的稳定遗迹。 这类粒子代表了一个有趣的物理目标，因为它们可以在高密度环境中迅速热化，从而规避直接探测现有的限制。 在这项工作中，我们指出它们在大型体积中微子望远镜内湮灭成可见物质可以提供一种约束或发现此类粒子的新方法。 对于GeV范围内的遗迹质量，信号最为显著，并且可以通过现有的超级神冈探测器双核子湮灭搜索有效地加以限制。 我们还以隐蔽暗物质耦合到暗光子的形式给出了这一情景的具体实现，并表明当前的方法对模型提出了新颖且严格的限制，这些限制补充了来自束流弃置实验、对撞机和直接探测实验的直接限制。 显示英文摘要

摘要： New particles in theories beyond the standard model can manifest as stable relics that interact strongly with visible matter and make up a small fraction of the total dark matter abundance. Such particles represent an interesting physics target since they can evade existing bounds from direct detection due to their rapid thermalization in high-density environments. In this work we point out that their annihilation to visible matter inside large-volume neutrino telescopes can provide a new way to constrain or discover such particles. The signal is the most pronounced for relic masses in the GeV range, and can be efficiently constrained by existing Super-Kamiokande searches for di-nucleon annihilation. We also provide an explicit realization of this scenario in the form of secluded dark matter coupled to a dark photon, and we show that the present method implies novel and stringent bounds on the model that are complementary to direct constraints from beam dumps, colliders, and direct detection experiments.
