"Table 59" of "Decomposing transverse momentum balance contributions for quenched jets in PbPb collisions at sqrt(s[NN]) = 2.76 TeV"

CERN-LHC. Decomposing transverse momentum balance contributions for quenched jets in PbPb collisions at 2.76 TeV with CMS Interactions between jets and the quark-gluon plasma produced in heavy ion collisions are studied via the angular distributions of summed charged-particle transverse momenta (pT) with respect to both the leading and subleading jet axes in high-pT dijet events. The contributions of charged particles in different momentum ranges to the overall event pT balance are decomposed into short-range jet peaks and a long-range azimuthal asymmetry in charged-particle pT. The results for PbPb collisions are compared to those in pp collisions using data collected in 2011 and 2013, at collision energy 2.76 TeV with integrated luminosities of 166 inverse microbarns and 5.3 inverse picobarns, respectively, by the CMS experiment at the LHC. Measurements are presented as functions of PbPb collision centrality, charged-particle pT, relative azimuth, and radial distance from the jet axis for balanced and unbalanced dijets. Dijet events are characterized by asymmetry parameter Aj = (pT1 - pT2)/(pT1 + pT2), where pT1 = transverse momentum of the leading (highest-pT) jet and pT2 = transverse momentum of the subleading (second-highest-pT) jet. The sample is divided into two asymmetry classes--more balanced dijets for which Aj < 0.22 (52% of the PbPb sample and 67% of the pp sample), and more unbalanced dijets for which Aj > 0.22.

本数据集源自欧洲核子研究中心（CERN）大型强子对撞机（LHC）上的紧凑缪子线圈（CMS, Compact Muon Solenoid）实验，针对2.76 TeV铅铅（PbPb）对撞中的淬火喷注横动量平衡贡献开展分解研究。在高横动量双喷注事件中，研究团队通过统计求和后的带电粒子总横动量（p_T）相对于领头喷注与次领头喷注轴的角分布，探究重离子对撞中产生的夸克胶子等离子体与喷注的相互作用。研究将不同动量区间内的带电粒子对整体事件横动量平衡的贡献，分解为短程喷注峰与带电粒子p_T的长程方位角不对称性两部分。
本研究利用LHC上CMS实验分别于2011年和2013年采集的数据，将铅铅对撞的实验结果与质子质子（pp）对撞的结果进行对比；两次数据采集的对撞能量均为2.76 TeV，对应的积分亮度分别为166 微靶倒数（μb⁻¹）与5.3 皮靶倒数（pb⁻¹）。
测量结果以铅铅对撞中心度、带电粒子p_T、相对方位角，以及平衡与非平衡双喷注事件中喷注轴的径向距离为函数形式进行呈现。
双喷注事件通过不对称性参数A_j = (p_T1 - p_T2)/(p_T1 + p_T2) 进行表征，其中p_T1为领头喷注（横动量最高的喷注）的横动量，p_T2为次领头喷注（横动量第二高的喷注）的横动量。
该实验样本被划分为两类不对称性区间：一类是A_j < 0.22的更平衡双喷注样本（占铅铅样本的52%、质子质子样本的67%），另一类是A_j > 0.22的更非平衡双喷注样本。
