We present the implementation in MadAnalysis 5 of the CMS-TOP-18-003 search for the production of four top quarks in the Standard Model and detail the validation of this implementation. This CMS analysis studies Standard Model four-top production through the same-sign and multi-lepton plus jets channels, using a luminosity of 137 fb[Formula: see text] of proton-proton collisions at a center-of-mass energy of 13 TeV. We validate our implementation work by studying various distributions and event counts describing the properties of the signal in the context of the Standard Model: jet and [Formula: see text]-jet multiplicities, the hadronic activity [Formula: see text], and the number of expected events populating the various analysis signal regions. We then provide a small example of usage of this implementation to constrain a toy new physics model.

在 MadAnalysis 5 框架中实施 CMS-TOP-18-003 分析(四个顶夸克,至少有两个轻子;137 fb-1)

我们在 CMS-TOP-18-003 的 MadAnalysis 5 中展示了在标准模型中搜索四个顶夸克的实现,并详细说明了该实现的验证。此 CMS 分析通过相同符号和多轻子加射流通道研究标准模型四顶生产,使用质心能量为 13 的质子-质子碰撞的光度为 137 fb[公式:见正文] TeV。我们通过研究描述标准模型上下文中信号属性的各种分布和事件计数来验证我们的实施工作:射流和[公式:见文本]-射流多重性、强子活动 [公式:见文本],以及填充各种分析信号区域的预期事件的数量。然后,我们提供了一个使用此实现来约束玩具新物理模型的小示例。
