"Table 147" 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-质子碰撞环境下，本研究针对顶夸克对（top quark pairs）的产生过程，测量了其随喷注多重度、顶夸克以及顶夸克-反顶夸克系统运动学变量变化的微分截面与双微分截面。本分析基于大型强子对撞机（Large Hadron Collider, LHC）上CMS实验采集的积分亮度为2.3 fb⁻¹的数据样本。本次测量选取末态包含单μ子或单电子的轻子+喷注衰变道开展。上述微分截面分别在贴近实验接收度的粒子级相空间，以及全相空间的部分子级下呈现。研究团队将本次测量结果与若干标准模型（Standard Model）的理论预言进行了对比。
