"Table 504" 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 $p_{T}^{t\bar{t}}$ at particle level in the resolved topology in 0.0 GeV < $p_{T}^{t\bar{t}}$ < 30.0 GeV. 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.

本数据集给出分辨拓扑下粒子层级上，以强子化顶夸克横向动量$p_{T}^{t,had}$与顶反顶对横向动量$p_{T}^{tar{t}}$为双变量的绝对双微分截面，其中顶反顶对横向动量的取值区间为0.0 GeV < $p_{T}^{tar{t}}$ < 30.0 GeV。需说明，此处展示的数值是通过将各单个不确定性传递至测得的截面得到的，而协方差矩阵则采用正文中所述的伪实验方法进行计算。本研究将测得的微分截面与使用Powheg+Pythia8蒙特卡洛生成器得到的理论预言进行了对比。
