"Table 4" 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.

在13 TeV质子-质子碰撞中，研究团队测量了顶夸克对产生的微分与双微分截面，测量结果依赖于喷注多重数、顶夸克及顶夸克-反夸克系统的运动学变量。本分析基于大型强子对撞机（Large Hadron Collider, LHC）上的CMS实验（Compact Muon Solenoid）采集的数据，该数据对应的积分亮度为2.3 fb⁻¹。本次测量针对末态包含单个μ子或电子的轻子+喷注衰变道开展。微分截面分别在接近实验接收度的相空间内的粒子级，以及全相空间内的部分子级下予以呈现。研究结果与若干标准模型（Standard Model）的理论预言进行了对比。
