"Table 404" 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 $\chi_{tt}$ vs $N^{jets}$ at particle level in the resolved topology in $N^{jets}$ = 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$N^{ ext{jets}}$=6.0的分辨拓扑结构的粒子层面上，以$chi_{tt}$为变量、随喷注数$N^{ ext{jets}}$变化的绝对双微分截面。请注意，此处展示的数值是通过将各单项不确定度传播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，借助伪实验（pseudo-experiments）进行计算。将本次测得的微分截面与使用Powheg+Pythia8蒙特卡洛（Monte Carlo, MC）生成器得到的理论预言进行了对比。
