"Table 37" 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 $N^{extra jets}$ 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.

分辨拓扑下，粒子级别的相对微分截面随额外喷注数$N^{extra jets}$变化。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得的截面后得到的，而协方差矩阵则按照文中所述方法利用伪实验进行计算。将测得的微分截面与使用Powheg+Pythia8蒙特卡洛（Monte Carlo）生成器得到的理论预言进行对比。
