"Table 98" 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.

CERN-LHC（欧洲核子研究中心大型强子对撞机）。本研究针对质心系能量7 TeV的质子-质子碰撞中产生的带电粒子喷注特性开展测量，采用最小偏置触发（minimum-bias trigger）进行数据采集。实验数据采集于2010年，积分亮度为779 μb⁻¹。喷注重建采用anti-kT算法（anti-kT algorithm），设置半径参数为0.4与0.6，应用于横向动量（Transverse Momentum，简称PT）大于300 MeV的带电粒子。基于径迹重建的喷注测量结果经校正后回溯至真实层面带电粒子喷注，后者定义为将相同算法应用于所有满足相同PT截断条件的初级带电粒子所得到的喷注。本工作给出了多维度测量结果，包括PT截面、每喷注多重数、碎裂Z分布、相对于喷注轴的横向动量与带电粒子径向密度，上述测量均在快度（rapidity）与横向动量的分箱区间内完成。2014年6月27日补充说明：下表1至表4中刊载的截面数值需乘以因子1.0187，以适配ATLAS实验2010年数据采集阶段更新后的积分亮度取值。全局归一化（“亮度（Lumi）”）的不确定度由3.4%小幅提升至3.5%。详细信息参见《Eur.Phys.J. C73 (2013) 2518》。
