"Table 176" of "Measurements of top-quark pair single- and double-differential cross-sections in the all-hadronic channel in $pp$ collisions at $\sqrt{s}=13~\textrm{TeV}$ using the ATLAS detector"

Covariance matrix between the relative double-differential cross-section as function of $p_{T}^{t,2}$ vs $N_{jets}$ in $N_{jets}$ > 8 and the relative double-differential cross-section as function of $p_{T}^{t,2}$ vs $N_{jets}$ in $N_{jets}$ = 6 at particle level in the all hadronic resolved topology, accounting for the statistical and systematic uncertainties.全强子分辨拓扑结构的粒子层面下，以顶夸克横向动量平方$p_{T}^{t,2}$与喷注数目$N_{jets}$为自变量的相对双微分截面（对应喷注数目$N_{jets}>8$的样本），与变量形式一致的相对双微分截面（对应$N_{jets}=6$的样本）之间的协方差矩阵，该矩阵已计入统计与系统不确定性。

背景与挑战

背景概述

该数据集是ATLAS实验在13 TeV质子-质子碰撞中全强子道顶夸克对产生截面测量的组成部分，具体为表格176，提供了粒子能级下第二个顶夸克横向动量（T2_PT）与喷注多重数（Njets）的双微分截面协方差矩阵数据，用于Njets>8和Njets=6情况的比较，数据基于36 fb⁻¹的积分亮度，旨在支持顶夸克产生特性的精确测试和理论预测验证。
