CERN-LHC. Measurements of charged-particle fragmentation functions of jets produced in ultra-relativistic nuclear collisions can provide insight into the modification of parton showers in the hot, dense medium created in the collisions. ATLAS has measured jets in sqrt(sNN) = 2.76 TeV PB PB collisions at the LHC using a data set recorded in 2011 with an integrated luminosity of 0.14 nb^{-1}. Jets were reconstructed using the anti-kt algorithm with distance parameter values R = 0.2, 0.3, and 0.4. Here is the summary of results for the charged particle (CH) longitudinal momentum fraction, Z = PT(CH).PT(JET)/ABS(PT(JET))**2, distributions, D(Z) = (1/N(JET))*D(N(CH))/DZ and distributions of transverse momenta of particles in jets, D(PT(CH)) = (1/N(JET))*D(N(CH))/DPT(CH). The jets have PT>100 GeV, |ETA|<2.1, and the particle to jet association is done using geometrical matching with DELTA R <= 0.4 for all three different R values.

欧洲核子研究中心大型强子对撞机（CERN-LHC）相关数据集：针对超相对论性核碰撞中产生的喷注的带电粒子碎裂函数开展的测量，可用于揭示碰撞所形成的热密介质内部分子簇射（parton showers）的修正效应。ATLAS探测器（ATLAS）依托大型强子对撞机上2011年采集的数据集，对质心系能量√s_NN=2.76太电子伏特（TeV）的铅-铅（Pb-Pb）碰撞中的喷注进行了测量，该数据集的积分亮度为0.14纳靶恩⁻¹（nb⁻¹）。本次分析采用anti-kt算法进行喷注重建，设置的距离参数R分别为0.2、0.3与0.4。本数据集包含两类分布结果：其一为带电粒子（CH）纵向动量份额Z = p_T(CH)·p_T(JET)/|p_T(JET)|²对应的分布D(Z)=(1/N_喷注)·dN(CH)/dZ；其二为喷注内粒子横向动量（PT）对应的分布D(p_T(CH))=(1/N_喷注)·dN(CH)/dp_T(CH)。所有入选喷注需满足横向动量p_T>100吉电子伏特（GeV）、快度|η|<2.1的要求，且针对三类不同R值的喷注，均采用ΔR≤0.4的几何匹配方法完成粒子与喷注的关联。
