论文摘要
自毁的暗物质（SDDM）是一类黑暗扇区模型，其中黑暗扇区粒子与地球的碰撞会诱导其迅速衰减到标准模型颗粒中，从而在中微子探测器上产生独特的信号。 SDDM的固有脆弱性使其从早期宇宙中生存，这意味着晚期生产机制。我们提出了基于原子重排的有效延迟生产机制，该机制是原子重排，该机制负责氢气中的MUON或抗蛋白捕获的机制。在此模型中，原子重排过程发生在我们的银河系中，将黑暗原子转化为高度激发的结合状态 - 我们的SDDM候选物。尽管所得的SDDM只是暗物质通量的一小部分，但其引人注目的自我毁灭信号意味着从Super-Kamiokande实验中的现有数据中发现了显着的发现。
Self-Destructing Dark Matter (SDDM) is a class of dark sector models in which the collision of a dark sector particle with the earth induces its prompt decay into Standard Model particles, generating unique signals at neutrino detectors. The inherent fragility of SDDM makes its survival from the early universe unlikely, implying a late time production mechanism. We present an efficient late time production mechanism for SDDM based on atomic rearrangement, the mechanism responsible for muon or anti-proton capture in hydrogen. In this model, an atomic rearrangement process occurs in our galaxy, converting dark atoms into highly excited bound states - our SDDM candidates. While the resulting SDDM is only a small fraction of the dark matter flux, its striking self-destruction signals imply a significant discovery reach in the existing data from the Super-Kamiokande experiment.
