"Table 299" 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.本文报道了顶夸克对（top-quark pair）产生过程的单微分截面与双微分截面（single- and double-differential cross-section）测量结果，该测量针对粒子层次（particle level）与部分子层次（parton level）下的分辨拓扑结构（resolved topology）全强子衰变道（all hadronic channel）。测量结果以多个表征顶夸克与$tar{t}$系统的运动学变量（kinematic variable）以及喷注多重数（jet multiplicity）为函数形式给出。本研究利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（ATLAS），在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，对应的积分亮度（integrated luminosity）为36 fb⁻¹。由于大型强子对撞机上$tar{t}$产生截面较大，此类测量可用于细致研究顶夸克产生与衰变的性质，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）预言的精确检验。总体而言，理论预言与实验数据之间展现出良好的一致性。
