论文摘要
在CERN的ATLAS实验中，提出了两个差异横截面测量值的初步结果。测量值集中在〜Lepton+喷气器中的顶部夸克对生产以及具有高横向动量顶部夸克的运动区域中的〜Ald-HADRONIC通道。这两种测量结果均使用来自ATLAS检测器在2015 - 2018年收集的大型强子对撞机的13个TEV质子 - 蛋白碰撞的2个数据，对应于139 fb $^{ - 1} $的集成光度。将测得的光谱与标准模型预测进行了比较。它们还用于对标准模型的有效场理论扩展的威尔逊系数设定限制。
Preliminary results of two differential cross-section measurements in the ATLAS experiment at CERN are presented. Measurements are focused on the top-antitop quark pair production in the~lepton+jets and the~all-hadronic channels in the kinematic region with high transverse momentum top quarks. Both measurements use the full Run 2 data of 13 TeV proton-proton collisions from the Large Hadron Collider collected by the ATLAS detector in 2015-2018, corresponding to an integrated luminosity of 139 fb$^{-1}$. The measured spectra are compared with the Standard Model predictions. They are also used to set limits on the Wilson coefficients of an effective field theory extension of the Standard Model.
