AI总结:

ATLAS和CMS实验通过比较理论预测与数据,研究顶夸克截面及干涉效应,发现高阶QCD预测能更准确描述数据。

摘要:

本报告总结了由ATLAS和CMS实验进行的差异顶夸克截面测量最近的结果。研究了$t\ar{t}$过程以及单(反)顶夸克的产生以及与其他标准模型过程相同最终状态的干涉。最先进的理论预测与数据进行比较。没有理论模型能够描述所有bin的数据,但当向perturbative QCD更高阶的预测过渡时,可以观察到数据的改进描述。

英文摘要:

This report summarizes recent results of differential top quark cross section measurements performed by the ATLAS and CMS experiments. The $t\bar{t}$ process is studied as well as the production of single (anti-)top quarks and the interference with other Standard Model processes of the same final state. State-of-the-art theory predictions are compared to the data. No theory model is able to describe the data across all bins, but an improved description of the data when moving to predictions in higher orders in perturbative QCD can be observed.
