"Table 1" of "Measurement of differential cross sections for top quark pair production using the lepton+jets final state in proton-proton collisions at 13 TeV"

Differential and double-differential cross sections for the production of top quark pairs in proton-proton collisions at 13 TeV are measured as a function of jet multiplicity and of kinematic variables of the top quarks and the top quark-antiquark system. This analysis is based on data collected by the CMS experiment at the LHC corresponding to an integrated luminosity of 2.3/fb. The measurements are performed in the lepton+jets decay channels with a single muon or electron in the final state. The differential cross sections are presented at particle level, within a phase space close to the experimental acceptance, and at parton level in the full phase space. The results are compared to several standard model predictions.

本研究针对13太电子伏特（TeV）质子-质子碰撞中顶夸克对的产生过程，测量了其作为喷注多重数、顶夸克及顶夸克-反夸克系统运动学变量函数的微分截面与双微分截面。本次分析基于大型强子对撞机（LHC）上紧凑型缪子线圈（CMS）实验采集的数据，对应积分亮度为2.3反飞母托靶恩（fb⁻¹）。测量在末态包含单个缪子或电子的轻子+喷注衰变道中开展。微分截面分别在接近实验接受度的相空间内的粒子层次，以及全相空间内的部分子层次上给出。研究结果与若干标准模型（Standard Model）的理论预言进行了对比。
