"Table 437" 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.

本研究针对粒子层级与部分子层级分辨拓扑结构下的全强子道顶夸克对产生过程，给出单微分与双微分截面的测量结果。该结果以多个表征顶夸克与$tar{t}$（top-antitop quark pair）系统以及喷注多重数的运动学变量作为函数形式呈现。本分析采用欧洲核子研究中心（CERN）大型强子对撞机（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-质子碰撞数据完成，对应积分亮度为36 fb⁻¹。鉴于大型强子对撞机上$tar{t}$截面数值可观，此类测量可实现顶夸克产生与衰变性质的精细研究，并能够对多款蒙特卡洛（Monte Carlo）发生器以及固定阶标准模型预言开展精确检验。总体而言，理论预言与实验数据之间展现出良好的一致性。
