论文摘要
我们提出了一种新的策略，以通过核捕获来搜索特定类型的暗物质。如果暗物质粒子携带Baryon数量，则是由宇宙物质抗对称不对称的一类理论解释所激发的，它可以与中子混合并被原子核捕获。通过发出单个光子或一组光子的级联，总能量的总能量最大为几位MEV来取消启用。该能量的确切值取决于暗物质质量。我们研究了在当前和将来的中微子和暗物质直接检测实验中检测暗物质捕获信号的前景。
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.
