相对论离子碰撞的一些软问题
Some soft aspects of relativistic ion collisions
摘要：
受伤核子和夸克参与者的概念多年来一直被用来参数化和/或解释高能核碰撞的许多特征。一些结果说明这两种方法的成功和失败，包括最新的发展。特别是，在CERN-SPS的NA 49实验测量的核碰撞确定的粒子生产的结果显示。利用核重叠模型对核子和组分夸克框架进行了研究。此外，还对SPS能强子-核碰撞的pT谱在正向快度（用核修正因子表示）下的行为作了初步的观察。这些结果与氘-金碰撞的RHIC结果有关，通常被解释为饱和和/或彩色玻璃冷凝物的表现。
英文摘要：
Concepts of wounded nucleon and quark participants have been used for years to parametrize and/or to explain many features of high energy nuclear collisions. Some results illustrating successes and failures of these two approaches are presented, including the latest developments. In particular, results on identified particle production from nuclear collisions measured by the NA49 experiment at the CERN-SPS are shown. The study has been done for both the nucleon and the constituent quark frameworks using the nuclear overlap model. In addition, some preliminary observations concerning the behavior of pT spectra at forward rapidities, expressed in terms of the nuclear modification factor, for hadron-nucleus collisions at the SPS energy are also presented. These results are in relevance to RHIC results for deuteron-gold collisions often interpreted as a manifestation of saturation and/or color glass condensate.
