"Table 20" of "Properties of jets measured from tracks in proton-proton collisions at center-of-mass energy sqrt(s) = 7 TeV with the ATLAS detector"

CERN-LHC. Measurement of the properties of charged particle jets produced in proton-proton collisions at a centre-of-mass energy of 7 TeV using a minimum-bias trigger. The data were taken during 2010 and have an integrated luminosity of 779 mub^{-1}. Jets are reconstructed using the anti-kT algorithm with radius parameters 0.4 and 0.6 applied to charged particles with PT > 300 MeV. The measured track-based jets are corrected back to truth-level charged particle jets, which are defined to be the jets obtained when the same algoerithm is applied to all primary charged particles with the same PT cut. Measurements of the PT cross sections, multiplicities per jet, fragmentation Z distributions, transverse momentum and charged particle radial densities relative to the jet axes are presented in slices of rapidity and transverse momentum. Note added (27 JUN 2014): The cross section values reported in Tables 1-4 below should be multiplied by a factor of 1.0187 to take into account the updated value of the integrated luminosity for the ATLAS 2010 data taking period. The uncertainty on the global normalisation ("Lumi") increases slightly from 3.4% to 3.5%. See Eur.Phys.J. C73 (2013) 2518 for more details.

欧洲核子研究中心大型强子对撞机（CERN-LHC）：在质心系能量为7 TeV的质子-质子碰撞中，采用最小偏倚触发（minimum-bias trigger）对产生的带电粒子喷注的性质开展测量。
实验数据采集于2010年，积分亮度为779 μb⁻¹。喷注通过anti-kT算法（anti-kT algorithm）重建，选取半径参数为0.4与0.6，应用于横向动量（PT，transverse momentum）大于300 MeV的带电粒子。测量得到的径迹型喷注（track-based jets）被修正至真实级带电粒子喷注，后者的定义为：使用相同算法，对所有满足相同PT截断条件的初级带电粒子进行重建所得到的喷注。
本工作报告了横向动量截面、每喷注多重数、碎裂Z分布、相对于喷注轴线的横向动量以及带电粒子径向密度的测量结果，所有测量均按照快度（rapidity）与横向动量进行分箱处理。
2014年6月27日补充说明：下表1至4中报告的截面数值需乘以因子1.0187，以计入ATLAS 2010年数据采集周期更新后的积分亮度值。整体归一化（"亮度"）的不确定度从3.4%小幅上升至3.5%。详细信息参见《欧洲物理杂志C辑》C73 (2013) 2518。
