"Table 78" 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"

Single- and double-differential cross-section measurements are presented for the production of top-quark pairs, in the all hadronic channel in the resolved topology at particle and parton level. The results are presented as a function of several kinematic variables characterising the top and $t\bar{t}$ system and jet multiplicities. The study was performed using data from pp collisions at centre-of-mass energy of 13 TeV collected in 2015 and 2016 by the ATLAS detector at the CERN Large Hadron Collider (LHC), corresponding to an integrated luminosity of 36 fb$^{−1}$. Due to the large $t\bar{t}$ cross-section at the LHC, such measurements allow a detailed study of the properties of top-quark production and decay, enabling precision tests of several Monte Carlo generators and fixed-order Standard Model predictions. Overall, there is good agreement between the theoretical predictions and the data.

本文报告了顶夸克对产生过程的单微分截面（single-differential cross-section）与双微分截面（double-differential cross-section）测量结果，测量覆盖粒子级与部分子级分辨拓扑结构下的全强子末态道。该结果以若干表征单个顶夸克与顶夸克-反顶夸克对（$tar{t}$）系统的运动学变量及喷注多重数为自变量给出。本研究使用欧洲核子研究中心（CERN）大型强子对撞机（Large Hadron Collider, LHC）上的ATLAS探测器，在2015年与2016年采集的质心系能量为13 TeV的质子-质子（pp）对撞数据开展，对应积分亮度为36 fb⁻¹。鉴于大型强子对撞机上顶夸克-反顶夸克对（$tar{t}$）的产生截面较大，此类测量可用于细致研究顶夸克的产生与衰变性质，从而实现对多款蒙特卡洛（Monte Carlo）发生器以及固定阶标准模型（Standard Model, SM）预言的精确检验。总体而言，理论预言与实验测量数据之间吻合度良好。
