论文摘要
讨论了在$ e^{+} e^{ - } $ colliders中产生的暗光子的搜索，随后将其腐烂成无弹性暗物质粒子。较重的暗物质在行驶一段距离后腐烂成一对可见的带电颗粒和一个较轻的暗物质粒子。可见的衰减产物可以通过由乳液和气体检测器制成的暗物质检测器记录，放置在主要$ e^{+} e^{ - } $检测器附近。该设置不仅可以探索以前未达到的新参数区域，而且还可以重新开放某些区域被认为被以前的实验数据排除在外。提出了这种检测器围绕BESIII和Belle II的物理潜力。
The search for a dark photon produced at $e^{+}e^{-}$ colliders which subsequently decays into inelastic dark matter particles, is discussed. The heavier dark matter decays into a pair of visible charged particles and a lighter dark matter particle after traveling some distance. The visible decay products can be recorded by a dark matter detector made of emulsions and gas detectors, placed near the main $e^{+}e^{-}$ detector. This setup can not only explore new parameter regions not reached before, but also re-open some regions thought to be excluded by previous experimental data. The physics potential for such a detector around BESIII and Belle II is presented.
