"Table 193" 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.

本文报道了粒子级与部分子级（parton level）分辨拓扑下全强子末态道中顶夸克对产生过程的单微分与双微分截面测量结果。测量结果以若干表征顶夸克与顶夸克-反夸克（$tar{t}$）系统以及喷注多重数的运动学变量为函数形式给出。本研究使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（pp）碰撞数据，对应的积分亮度为36 fb⁻¹。鉴于大型强子对撞机上顶夸克对产生截面较大，此类测量可实现顶夸克产生与衰变性质的精细研究，从而为多款蒙特卡洛（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展现出良好的一致性。
