In this paper, we present the MadAnalysis 5 implementation of the CMS-EXO-19-002 analysis, probing an excess of events featuring multiple charged leptons in LHC proton–proton collisions at [Formula: see text]. The original analysis is based on data acquired by the CMS detector during the 2016–2018 campaign, which corresponds to an integrated luminosity of 137 fb[Formula: see text]. Data have been tested against hypothetical extensions of the Standard Model where additional leptons can stem from new heavy fermion decays or from new light scalar/pseudoscalar decays. The CMS selection has been fully implemented in the MadAnalysis 5 platform and successfully validated by reproducing official results in the form of signal distributions at the end of the selection.

在 MadAnalysis 5 框架中实现 CMS-EXO-19-002 搜索（具有多轻子最终状态的标准模型之外的物理；137 fb-1）

在本文中，我们介绍了 CMS-EXO-19-002 分析的 MadAnalysis 5 实现，在 [公式：见正文] 处探测 LHC 质子 - 质子碰撞中具有多个带电轻子的过量事件。原始分析基于 CMS 探测器在 2016-2018 年活动期间获取的数据，对应的综合光度为 137 fb[公式：见正文]。数据已经针对标准模型的假设扩展进行了测试，其中额外的轻子可能来自新的重费米子衰变或新的轻标量/伪标量衰变。CMS 选择已在 MadAnalysis 5 平台中全面实施，并通过在选择结束时以信号分布的形式再现官方结果来成功验证。
