利用大型强子对撞机ATLAS探测器收集的数据，对中性、弱相互作用、长寿命粒子的衰变进行了研究。本文的分析使用了2015-2016年记录的质子-质子碰撞数据。搜索采用的技术重建的长寿命粒子的顶点衰变成射流的μ子光谱仪利用两个顶点的策略和一种新的技术，只需要一个顶点与检测器中的额外活动，提高了灵敏度更长的寿命。观察到的事件数量与预期背景一致，并确定了几个基准信号的限值。
A search for the decay of neutral, weakly interacting, long-lived particles using data collected by the ATLAS detector at the LHC is presented. The analysis in this paper usesof proton-proton collision data atrecorded in 2015–2016. The search employs techniques for reconstructing vertices of long-lived particles decaying into jets in the muon spectrometer exploiting a two-vertex strategy and a novel technique that requires only one vertex in association with additional activity in the detector that improves the sensitivity for longer lifetimes. The observed numbers of events are consistent with the expected background and limits for several benchmark signals are determined.
