资源简介:
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].
本数据集呈现了针对夸克引发射流与胶子引发射流的组成结构的喷注子结构测量结果。研究使用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,对应的积分亮度为35.9 fb⁻¹。
本次测量采用广义角距(generalized angularities)以表征喷注子结构,并区分夸克引发与胶子引发射流。该类观测量对射流内部的横向动量分布与角间距具有敏感性。
分析工作使用了富含胶子引发射流的双喷注事件样本,并首次采用了富含夸克引发射流的Z+射流事件样本。观测量按喷注横向动量的分箱形式给出,并作为喷注半径参数的函数进行呈现。每项测量均重复应用了可移除射流中软辐射与大角度辐射的“软滴(soft drop)”修整程序。
为便于查阅,图表命名采用编码规则,各字母/数字依次代表:未修整/经修整、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+射流、PT]。
