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):利用最小偏置触发(minimum-bias trigger),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的性质开展测量。该数据采集于2010年,积分亮度为779 μb⁻¹。喷注采用反kT算法(anti-kT algorithm)重建,半径参数分别为0.4和0.6,应用于横向动量(Transverse Momentum, PT)大于300 MeV的带电粒子。所测量的径迹型喷注被校正至真实级带电粒子喷注,后者定义为将相同算法应用于所有满足相同横向动量截断的初级带电粒子所得到的喷注。本文给出了快度和横向动量分箱下,横向动量(PT)截面、单喷注多重数、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 2010年取数时段的积分亮度更新值,下述表1至表4中报告的截面数值需乘以因子1.0187。整体归一化("Lumi")的不确定度从3.4%小幅升至3.5%。更多细节详见《欧洲物理杂志C辑》(Eur.Phys.J. C)73卷(2013年)第2518号论文。
