在事件-事件（3+1）维粘性流体力学的框架下，研究了sNN=5.02 TeV LHC能量下pPb碰撞的两粒子相对速度和方位关系。研究发现，在多重度最高的事件中，观测到的脊结构以一种自然的方式出现，这表明集体流动可能是系统演化的一个重要因素。我们还讨论了电荷平衡和横向动量守恒的作用。
Two-particle correlations in relative rapidity and azimuth are studied for the pPb collisions at the LHC energy of sNN=5.02 TeV in the framework of event-by-event (3+1)-dimensional viscous hydrodynamics. It is found that for the highest-multiplicity events the observed ridge structures appear in a natural way, suggesting that collective flow may be an important element in the evolution of the system. We also discuss the role of the charge balancing and the transverse-momentum conservation.
