摘要
本文讨论了高能重离子碰撞中的两种非线性效应——次级粒子的相互作用以及不等核过程的核内级联;分析了它们对末态粒子分布,特别是未态分布对靶核依赖性的影响;用流体力学模型具体计算了快度分布的靶核依赖因子,计算结果与实验基本符合.
In this paper, we discuss two non-linear effects in high energy heavy ion collisions, intranuclear cascade and interaction between the secondaries. Their influence on the distributions of final state particles, especially on the target mass dependence of these distributions is analysed. Using hydrodynamical model, we calculated the distributions and compared their target mass, dependence with existing data.
