DESY-HERA. Measurement of the jet substructure and differential cross sections for jets produced in the photoproduction and DIS scattering regions in E P collisions (E+-=27.5 GeV,P=920 GeV) with an integrated luminosity of 82.2 pb-1. The substructure of jets is studied in terms of the jet shape and subjet multiplicity for jets with transverse energies & gt; 17 GeV. The jet shapes and subjet multiplicities are used to tag gluon and quark initiated jets. (BROAD and NARROW respectively). See text of paper for details.. R is the core radius in the KT cluster jet finding algorithm.. YCUT is the jet resolution parameter.

DESY-HERA实验数据集：在正负电子质子（e⁺p）碰撞（束流能量E₊⁻=27.5 GeV，质子束能量p=920 GeV）、积分亮度为82.2 pb⁻¹的实验条件下，对光生区域与深度非弹性散射（Deep Inelastic Scattering, DIS）散射区域内产生的喷注的喷注子结构与微分截面进行测量。针对横向能量大于17 GeV的喷注，本实验通过喷注形状与子喷注多重数来研究其喷注子结构。喷注形状与子喷注多重数可用于标记胶子引发与夸克引发的喷注（分别对应宽喷注与窄喷注）。详细信息请参见论文正文。R为KT簇聚喷注重建算法（KT cluster jet finding algorithm）中的核心半径，YCUT为喷注分辨参数。
