"Table 206" 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.

本研究报道了粒子层次（particle level）与部分子层次（parton level）下，分辨型拓扑结构中全强子末态道的顶夸克对（top-quark pairs）产生过程的单微分与双微分截面（single- and double-differential cross-section）测量结果。上述结果以多个运动学变量（kinematic variables）为函数形式呈现，这些变量用于表征顶夸克以及顶夸克-反顶夸克（$tar{t}$）系统和喷注多重数（jet multiplicities）。
本研究依托欧洲核子研究中心（CERN）大型强子对撞机（Large Hadron Collider, LHC）上的ATLAS探测器（ATLAS detector），使用2015年与2016年采集的质心系能量（centre-of-mass energy）为13 TeV的质子-质子（pp）碰撞数据开展，对应积分亮度（integrated luminosity）达36 fb⁻¹。
鉴于大型强子对撞机上顶夸克-反顶夸克对的产生截面较大，此类测量能够实现顶夸克产生与衰变性质的细致研究，进而为多款蒙特卡洛（Monte Carlo）发生器以及固定阶标准模型（Standard Model）预言提供精确检验。总体而言，理论预言与实验数据之间吻合度良好。
