"Extra Figure u4cL[f65]" 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].

本工作给出了描述夸克引发喷注与胶子引发喷注组成的喷注子结构测量结果。分析采用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，对应积分亮度为35.9 fb⁻¹。本研究测量了可表征喷注子结构、并区分夸克与胶子引发喷注的广义角距可观测量，此类可观测量对喷注内部的横向动量分布与角间距具有敏感性。分析样本包含富含胶子引发喷注的双喷注事件，同时首次使用了富含夸克引发喷注的Z+喷注事件样本。上述可观测量以喷注横向动量的分箱形式进行测量，并以喷注半径参数为变量展开测量。每项测量均重复执行了软滴（Soft Drop）清洗程序，该程序可移除喷注内的软辐射与大角度辐射。为便于检索查阅，所有图表均采用编码命名，各字母/数字的含义按顺序依次为：未清洗/已清洗、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、PT]。
