"Extra Figure g4cw[c800] (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].

本数据集呈现了描述夸克引发喷注与胶子引发喷注组成的喷注子结构（jet substructure）测量结果。实验采用CMS探测器（CMS）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。研究测量了用于表征喷注子结构、区分夸克与胶子引发喷注的广义角距（Generalized angularities）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敏感。分析使用了胶子喷注富集的双喷注（dijet）事件样本，并首次采用了夸克喷注富集的Z+喷注事件样本。可观测量按喷注横向动量分箱进行测量，同时也作为喷注半径参数的函数进行测量。每项测量均分别在未清理与经软滴（Soft Drop）清理的工况下完成，其中软滴清理流程可移除喷注内的软辐射与大角度辐射。为便于检索，图表采用编码命名，每个字母/数字依次代表：未清理/已清理、AK4/AK8、带电粒子、多重数/pTD2/喷注推力/喷注宽度/LHA、[中心区双喷注/向前区双喷注/Z+喷注、横向动量]。
