CMS μ子探测器的性能和$\sqrt{s}=$ 13 TeV质子-质子碰撞的μ子重建

Performance of the CMS muon detector and muon reconstruction with proton-proton collisions at $\sqrt{s}=$ 13 TeV

CMS Collaboration

摘要:

CMS μ子探测器系统、μ子重建软件和高水平触发器在2013-2014年经历了重大变化,为在更高的碰撞能量和瞬时光度下运行做准备。使用2015年和2016年在LHC收集的质心能量为$\sqrt{s}=$ 13 TeV的质子-质子碰撞数据研究了修改后系统的性能。所测得的性能参数,包括空间分辨率,效率和时间,被发现符合所有的设计规格,并通过仿真很好地再现。尽管更具有挑战性的运行条件下,修改后的μ子系统被发现执行以及,并在许多方面比以前更好。我们将这篇论文献给Alberto Benvenuti教授,他的工作是CMS μ子探测器的基础。

英文摘要:

The CMS muon detector system, muon reconstruction software, and high-level trigger underwent significant changes in 2013-2014 in preparation for running at higher LHC collision energy and instantaneous luminosity. The performance of the modified system is studied using proton-proton collision data at center-of-mass energy $\sqrt{s}=$ 13 TeV, collected at the LHC in 2015 and 2016. The measured performance parameters, including spatial resolution, efficiency, and timing, are found to meet all design specifications and are well reproduced by simulation. Despite the more challenging running conditions, the modified muon system is found to perform as well as, and in many aspects better than, previously. We dedicate this paper to the memory of Prof. Alberto Benvenuti, whose work was fundamental for the CMS muon detector.
