"Extra Figure g8cp[f186]" 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].

本数据集提供了用于描述夸克起源与胶子起源喷注组分的喷注子结构测量结果。实验使用CMS探测器（CMS）采集了质心系能量√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。研究人员测量了广义角距度，该可观测量可用于表征喷注子结构并区分夸克起源与胶子起源喷注。此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。本分析采用了两类事件样本：一类是富含胶子起源喷注的双喷注事件样本，另一类是首次采用的富含夸克起源喷注的Z+喷注事件样本。上述可观测量按照喷注横向动量的分箱进行测量，并以喷注半径参数为函数进行呈现。每一项测量均重复执行了“软滴”修整程序，该程序可移除喷注中的软辐射与大角度辐射。为便于查阅，图表采用编码方式命名，各字母/数字的含义按以下顺序依次对应：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）]。
