"Table 985" 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 $p_{T}^{t,had}$ vs $N^{extra jets}$ at particle level in the boosted topology in $N^{extra jets}$ $\geq$ 3.0. 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.

本数据集展示了在$N^{extra jets}≥3.0$的boosted拓扑（boosted topology）粒子级层面中，以强子化顶夸克横向动量$p_{T}^{t,had}$为函数、随额外喷注数$N^{extra jets}$变化的相对双微分截面。需注意，此处展示的数值是通过将各独立不确定度传递至实测截面后得到的，而协方差矩阵则按照正文中所述方法，借助伪实验（pseudo-experiments）计算得到。将测得的微分截面与采用Powheg+Pythia8蒙特卡洛（Monte Carlo）发生器得到的理论预言进行对比。
