"Table 992" 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"

Absolute double-differential cross-section as a function of $p_{T}^{t,had}$ vs $N^{extra jets}$ at particle level in the boosted topology in $N^{extra jets}$ = 0.5. 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.

粒子级boost型拓扑（boosted topology）下，以$p_{T}^{t,had}$与$N^{extra jets}$为双变量的绝对双微分截面，其中$N^{extra jets}$取值为0.5。需注意，此处展示的数值通过将各单个不确定度传递至实测截面得到，而协方差矩阵则按照正文所述方法，借助伪实验（pseudo-experiments）进行评估。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对比。
