"Extra Figure u4ct[c326] (corr)" of "Study of quark and gluon jet substructure in Z+jet and dijet events from pp collisions"

Measurements of jet substructure describing the composition of quark- and gluon-initiated jets are presented. Proton-proton (pp) collision data at sqrt(s)=13 TeV collected with the CMS detector are used, corresponding to an integrated luminosity of 35.9/fb. Generalized angularities are measured that characterize the jet substructure and distinguish quark- and gluon-initiated jets. These observables are sensitive to the distributions of transverse momenta and angular distances within a jet. The analysis is performed using a data sample of dijet events enriched in gluon-initiated jets, and, for the first time, a Z+jet event sample enriched in quark-initiated jets. The observables are measured in bins of jet transverse momentum, and as a function of the jet radius parameter. Each measurement is repeated applying a "soft drop" grooming procedure that removes soft and large angle radiation from the jet.For easier navigation, figures are named with a code with each letter/number representing in the following order: ungroomed/groomed, AK4/AK8, charged, multiplicity/pTD2/thrust/width/LHA, [central dijet/forward dijet/Z+jet, PT].

本数据集提供了表征夸克引发与胶子引发喷注组成的喷注子结构测量结果。实验采用CMS探测器采集的质心系能量√s=13 TeV的质子-质子（pp）碰撞数据，对应的积分亮度为35.9 fb⁻¹。研究测量了用于刻画喷注子结构、区分夸克与胶子引发喷注的广义角距度（Generalized angularities）。该类可观测量对喷注内部的横向动量分布与角距离分布具有敏感性。分析使用了两类事件样本：一类为富含胶子引发喷注的双喷注事件样本，另一类为首次采用的富含夸克引发喷注的Z+喷注事件样本。可观测量的测量按照喷注横向动量的分箱形式展开，并以喷注半径参数为变量进行表征。所有测量均分别执行了软滴（soft drop）修整程序，该程序可移除喷注内的软辐射与大角度辐射。为便于查阅，图表采用代码命名，各字符/数字的含义依次为：未修整/已修整、AK4/AK8、带电粒子、多重数/pTD2/推力/宽度/LHA、[中心区双喷注/前向区双喷注/Z+喷注、横向动量（PT）]。
