"Table 424" 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"

Covariance matrix between the Relative double-differential cross-section as function of $p_{T}^{t,had}$ vs $|y^{t,had}|$ in 1.4 < $|y^{t,had}|$ < 2.5 and the Relative double-differential cross-section as function of $p_{T}^{t,had}$ vs $|y^{t,had}|$ in 1.4 < $|y^{t,had}|$ < 2.5 at particle level in the resolved topology, accounting for the statistical and systematic uncertainties.

该数据集为协方差矩阵，表征两组相对双微分截面（Relative double-differential cross-section）之间的协方差：第一组为快度绝对值$|y^{t,had}|$处于1.4 < $|y^{t,had}|$ < 2.5区间内、以强子顶夸克横向动量$p_{T}^{t,had}$与快度绝对值$|y^{t,had}|$为变量的相对双微分截面；第二组为分辨拓扑（resolved topology）下粒子层面、相同快度区间与变量的相对双微分截面，且该协方差矩阵计入了统计与系统不确定性。
