"Extra Figure g4m[f481]" 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].

本数据集呈现了用于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。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，对应积分亮度为35.9 fb⁻¹。研究测量了广义角距（generalized angularities），该观测量可表征喷注子结构并区分夸克与胶子引发的喷注。此类观测量对喷注内部的横向动量分布与角间距具有敏感性。分析采用了胶子喷注占优的双喷注事件样本，同时首次使用了夸克喷注占优的Z+喷注事件样本。观测量按喷注横向动量分箱进行测量，并以喷注半径参数为函数进行表征。每项测量均重复应用了"soft drop"修整程序，以去除喷注内的软辐射与大角度辐射。为便于查阅，图表采用编码命名，各字母/数字依次代表：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/向前区双喷注/Z+喷注、PT]。
