Abstract

The current status of the searches for exotic, long-lived particles with the CMS experiment at $\sqrt{s}=13$ TeV is presented. Many theories beyond the Standard Model predict long-lived particles, for which different search approaches are utilized from those used in prompt searches. The searches discussed include the latest results at the time of the conference and cover a wide range of signatures. Searches for exotic, long-lived particles using inclusive displaced jets, displaced vertices in multijet events, disappearing tracks, heavy stable charged particles, and stopped particles are discussed, as well as reinterpretations of two recently published prompt searches, which complement the dedicated searches. The search and results are summarized for each analysis.

用CMS实验寻找长寿命粒子
介绍了在$\sqrt{s}=13$ TeV下用CMS实验寻找外来长寿命粒子的现状。标准模型之外的许多理论预测了长寿命粒子,对于这些粒子,使用了不同于即时搜索的搜索方法。讨论的搜索包括会议召开时的最新结果,涵盖了广泛的签名。本文讨论了用包含位移喷流、多喷流事件中的位移顶点、消失轨迹、重稳定带电粒子和停止粒子来搜索奇异的、长寿命的粒子,以及对最近发表的两种提示搜索的重新解释,它们补充了专门的搜索。为每个分析总结了搜索和结果。
