    讲述问题:流膂力学视角下的绝对论重离子碰撞中的粒子联系关系

    讲述人:钱卫良副传授(巴西圣保罗大学)

    讲述地址:中博一分快三彩票网三楼集会室(SL310)

    讲述择要:

    This presentation is aimed at discussions of particle correlation in relativistic heavy-ion collisions (RHIC). We briefly review the generic definitions of correlation, as well as particle correlation, which are encountered in mathematics and physics. Besides the general properties of particle correlations in field theory and quantum statistics, the emphasis is also given for the cases where correlation strength does not decrease with increasing multiplicities. Subsequently, we enumerate various types of two-particle correlations associated with RHIC and present the results, which demonstrate that the observed "ridge" effect in RHIC can be attributed to a collective phenomenon. To understand the latter, we discuss the physics of the hydrodynamic approach for RHIC as well as its specific role in the study of two-particle correlations. A peripheral tube model, as well as its implications, is explored.
