"Extra Figure g8cL[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].本工作报道了表征夸克引发喷注与胶子引发喷注组分的喷注子结构测量结果。实验使用质心系能量√s=13 TeV的质子-质子（pp）碰撞数据，该数据由CMS探测器采集，对应积分亮度为35.9 fb⁻¹。我们测量了广义角距（generalized angularities），此类可观测量可用于表征喷注子结构并区分夸克与胶子引发的喷注。此类可观测量对喷注内部的横向动量分布与角间距分布具有敏感性。本分析采用了富含胶子引发喷注的双喷注事件样本，并首次使用了富含夸克引发喷注的Z+喷注事件样本。上述可观测量按喷注横向动量分箱进行测量，同时以喷注半径参数为函数进行表征。每一项测量均重复应用"软降"（soft drop）喷注修整程序，该程序可移除喷注中的软辐射与大角度辐射。为便于查阅，所有图表采用编码命名，编码的每一位字符/数字依次代表：未修整/已修整、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/前向区双喷注/Z+喷注、横向动量]。
