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）数据集：针对质心系能量为7 TeV的质子-质子碰撞中产生的带电粒子喷注性质开展测量，实验采用最小偏置触发（minimum-bias trigger）。该数据集采集于2010年，积分亮度为779 μb⁻¹。喷注通过反kT算法（anti-kT algorithm）重建，半径参数取0.4与0.6，且仅对横向动量（transverse momentum, PT）大于300 MeV的带电粒子应用该算法。基于径迹重建的喷注被校正至真实级带电粒子喷注；真实级喷注的定义为，对所有满足相同横向动量截断条件的初级带电粒子应用同一算法所得到的喷注。本工作给出了在快度与横向动量区间内，横向动量截面、每喷注多重数、碎裂Z分布、相对于喷注轴的横向动量以及带电粒子径向密度的测量结果。2014年6月27日补充说明：考虑到ATLAS实验2010年数据采集阶段积分亮度的更新值，下述表1至表4中给出的截面数值需乘以因子1.0187。整体归一化的不确定度（"亮度"，记为Lumi）由3.4%小幅上升至3.5%。更多细节可参考《欧洲物理杂志C辑》（Eur.Phys.J. C）73卷（2013年）第2518号论文。
