"Table 53" 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"

Total cross-section 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 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的总截面。请注意，此处展示的数值是通过将各分项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，通过伪实验（pseudo-experiments）计算得到。将测得的截面与采用Powheg+Pythia8蒙特卡洛生成器得到的理论预言进行对比。
