"Table 204" 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 double-differential cross-section as a function of $m^{t\bar{t}}$ vs $N^{jets}$ at particle level in the resolved topology in $N^{jets}$ $\geq$ 6.0. 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.

在喷注数（$N^{jets}$）≥6.0的分辨拓扑结构中，粒子级层面上以顶夸克-反顶夸克对不变质量（$m^{tar{t}}$）与喷注数为变量的相对双微分截面。需注意，此处展示的数值通过将各单项不确定度传递至测得的截面得到，而协方差矩阵则采用正文中所述的伪实验方法计算得到。将测得的微分截面与采用Powheg+Pythia8蒙特卡洛生成器得到的理论预言进行了对比。
