论文摘要
预计四个顶级夸克的标准模型产生的序列为12FB。 CMS协作为这种罕见的生产机制提供了新的结果，用于在2016年至2018年收集的2个TEV收集的2个数据，考虑到含有零至四个电子或MUON的事件特征。这是在四个顶级夸克的研究中首次研究全部热通道，这是通过基于机器学习的新型基于数据驱动的背景估计技术而成为可能的。
The standard model production of four top quarks is predicted to have a cross section of the order of 12fb. The CMS Collaboration presents new results on this rare production mechanism for Run 2 data collected in 2016 through 2018 at 13 TeV, considering event signatures containing zero to four electrons or muons. This is the first time the all-hadronic channel is investigated in the study of four top quarks, made possible through novel machine learning based data-driven background estimation techniques.
