论文摘要
总结了LHC的CMS实验的最新结果，该结果与Z玻色子或光子相关联，以及四个顶级夸克的产生。使用了在13 TEV质量中心能量收集的质子 - 普罗顿碰撞数据，该数据对应于高达138 fb $^{ - 1} $的集成光度。在测得的结果中，最精确的包含横截面，显示了超出标准模型和首次差异测量的模型的大多数严格限制。总体而言，观察到与标准模型预测的良好一致。
Latest results from the CMS experiment at the LHC on top quark production in association with a Z boson or a photon, and the production of four top quarks, are summarized. Proton-proton collision data corresponding to an integrated luminosity of up to 138 fb$^{-1}$, collected at 13 TeV center-of-mass energy are used. Among the measured results, most precise inclusive cross sections, most stringent limits on models beyond the standard model and first differential measurements are presented. Overall, good agreement with standard model predictions is observed.
