"Table 41" of "Measurements of top-quark pair differential and double-differential cross-sections in the $\ell$+jets channel with $pp$ collisions at $\sqrt{s}=13$ TeV using the ATLAS detector"

Relative differential cross-section as a function of $|y^{t\bar{t}}|$ at particle level in the resolved topology. Note that the values shown here are obtained by propagating the individual uncertainties to the measured cross-sections, while the covariance matrices are evaluated using pseudo-experiments as described in the text. The measured differential cross-section is compared with the prediction obtained with the Powheg+Pythia8 Monte Carlo generator.

分辨拓扑结构下，粒子层面上以$|y^{tar{t}}|$为变量的相对微分截面。需注意，此处展示的数值是通过将各独立不确定度传递至测量截面得到的，而协方差矩阵则按照正文中所述方法，利用伪实验进行计算。将该测量得到的微分截面与使用Powheg+Pythia8蒙特卡洛生成器得到的理论预言进行对比。
