摘要:

μ子的识别对于LHCb的物理计划至关重要。在升级阶段,从LHC的运行3开始,实验的触发将完全基于软件。亮度增加到$2\times10^{33}$ cm $^{-2}$ s $^{-1}$将需要改进μ子识别标准,目标是性能等于或优于运行2,但在更具挑战性的环境中。在本文中,两个新的μ子识别算法开发的LHCb升级,并显示其性能的信号效率与背景减少。

英文摘要:

Muon identification is of paramount importance for the physics programme of LHCb. In the upgrade phase, starting from Run 3 of the LHC, the trigger of the experiment will be solely based on software. The luminosity increase to $2\times10^{33}$ cm$^{-2}$s$^{-1}$ will require an improvement of the muon identification criteria, aiming at performances equal or better than those of Run 2, but in a much more challenging environment. In this paper, two new muon identification algorithms developed in view of the LHCb upgrade are presented, and their performance in terms of signal efficiency versus background reduction is shown.
