摘要
采用核-核碰撞的Glauber模型,给出了高能重离子碰撞中的参与者数和核子-核子碰撞数随碰撞参数的分布方程,并用其讨论了(sNN)^(1/2)=200GeV的Au+Au碰撞中的参与者数与核子-核子碰撞数随对心度的变化关系,所得结果与PHENIX合作组所给出的实验结果符合得很好.
By using the Glauber model of nucleus-nucleus collision, we present the distribution equations for the numbers of participants and nucleon-nucleon collisions versus the impact parameter in high-energy heavy-ion collisions, and analyze with them the centrality dependence of both numbers in s_ NN =200?GeV Au+Au collisions. The results fit well with those given by PHENIX Collaboration.
