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.

欧洲核子研究中心大型强子对撞机（CERN-LHC）数据集。本研究利用紧凑渺子线圈（CMS）探测器，针对2.76 TeV铅铅（PbPb）对撞中的淬火喷注（quenched jets）开展横向动量平衡贡献的分解分析。研究通过高横向动量（transverse momentum, p_T）双喷注事件（dijet events）中，相对于领头喷注与次领头喷注轴的总带电粒子p_T的角分布，探究重离子对撞中产生的夸克胶子等离子体（quark-gluon plasma）与喷注的相互作用。本研究将不同动量区间内带电粒子对整体事件横向动量平衡的贡献，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（azimuthal asymmetry）两个部分。
我们使用CMS实验在大型强子对撞机上于2011年和2013年采集的2.76 TeV对撞数据进行分析：铅铅对撞数据的积分亮度（integrated luminosity）为166 逆微靶恩，质子质子（pp）对撞数据的积分亮度为5.3 逆皮靶恩，并将铅铅对撞的测量结果与质子质子对撞的结果进行对比。
本次测量结果以铅铅对撞中心度（centrality）、带电粒子p_T、相对方位角，以及平衡与非平衡双喷注的喷注轴径向距离作为函数形式呈现。双喷注事件通过不对称参数A_j = (p_T1 - p_T2)/(p_T1 + p_T2)进行表征，其中p_T1为领头（最高p_T）喷注的横向动量，p_T2为次领头（第二高p_T）喷注的横向动量。
本数据集将样本划分为两类不对称性组别：A_j < 0.22的高平衡度双喷注（占铅铅样本的52%、质子质子样本的67%），以及A_j > 0.22的低平衡度双喷注。
