"Table 43" of "Long-range two-particle correlations of strange hadrons with charged particles in pPb and PbPb collisions at LHC energies"

CERN-LHC. Measurements of two-particle angular correlations between an identified strange hadron (K0S or Lambda/anti-Lambda) and a charged particle, emitted in pPb collisions, are presented over a wide range in pseudorapidity and full azimuth. The data, corresponding to an integrated luminosity of approximately 35 inverse nanobarns, were collected at a nucleon-nucleon center-of-mass energy (sqrt(s[NN])) of 5.02 TeV with the CMS detector at the LHC. The results are compared to semi-peripheral PbPb collision data at sqrt(s[NN]) = 2.76 TeV, covering similar charged-particle multiplicities in the events. The observed azimuthal correlations at large relative pseudorapidity are used to extract the second-order (v[2]) and third-order (v[3]) anisotropy harmonics of K0S and Lambda/anti-Lambda particles. These quantities are studied as a function of the charged-particle multiplicity in the event and the transverse momentum of the particles. For high-multiplicity pPb events, a clear particle species dependence of v[2] and v[3] is observed. For pt < 2 GeV, the v[2] and v[3] values of K0S particles are larger than those of Lambda/anti-Lambda particles at the same pt. This splitting effect between two particle species is found to be stronger in pPb than in PbPb collisions in the same multiplicity range. When divided by the number of constituent quarks and compared at the same transverse kinetic energy per quark, both v[2] and v[3] for K0S particles are observed to be consistent with those for Lambda/anti-Lambda particles at the 10% level in pPb collisions. This consistency extends over a wide range of particle transverse kinetic energy and event multiplicities.欧洲核子研究中心大型强子对撞机（CERN-LHC）数据集：本文报道了质子-铅（pPb）碰撞中，已鉴别奇异强子（K⁰_S或Λ/反Λ）与带电粒子之间的双粒子角关联测量结果，测量覆盖了较宽的赝快度范围与全方位角区间。本次测量使用LHC上的CMS探测器，在核子-核子质心系能量√s_NN = 5.02 TeV条件下采集数据，对应积分亮度约为35纳靶恩（nb⁻¹）。研究将该结果与√s_NN = 2.76 TeV下的半外周铅铅（PbPb）碰撞数据进行对比，后者的事件带电粒子多重数与本次测量范围相近。通过观测大相对赝快度区间的方位角关联，我们提取得到K⁰_S及Λ/反Λ粒子的二阶（v₂）与三阶（v₃）各向异性流谐波。我们针对这些物理量，分别以事件带电粒子多重数与粒子横动量（p_T）为变量开展系统研究。在高多重数pPb碰撞事件中，我们观测到v₂与v₃存在显著的粒子种类依赖效应。当横动量p_T < 2 GeV时，相同p_T条件下K⁰_S粒子的v₂与v₃值均大于Λ/反Λ粒子。在相同多重数区间内，该两种粒子间的分裂效应在pPb碰撞中表现得比PbPb碰撞更为显著。当将物理量除以组分夸克数目，并以每夸克的横向动能为标尺进行对标时，我们发现在pPb碰撞中，K⁰_S粒子的v₂与v₃值在10%的误差范围内与Λ/反Λ粒子保持一致。该一致性覆盖了较宽的粒子横向动能与事件多重数区间。
