Abstract We propose a new strategy to search for a particular type of dark matter via nuclear capture. If the dark matter particle carries baryon number, as motivated by a class of theoretical explanations of the matter-antimatter asymmetry of the universe, it can mix with the neutron and be captured by an atomic nucleus. The resulting state de-excites by emitting a single photon or a cascade of photons with a total energy of up to several MeV. The exact value of this energy depends on the dark matter mass. We investigate the prospects for detecting dark matter capture signals in current and future neutrino and dark matter direct detection experiments.

原子核捕获暗物质

摘要 我们提出了一种通过核捕获来寻找特定类型暗物质的新策略。如果暗物质粒子带有重子数，那么在宇宙物质-反物质不对称的一类理论解释的推动下，它可以与中子混合并被原子核捕获。由此产生的状态通过发射单个光子或总能量高达几个 MeV 的光子级联来去激发。该能量的确切值取决于暗物质的质量。我们研究了在当前和未来的中微子和暗物质直接探测实验中探测暗物质捕获信号的前景。
