高能金-金碰撞末态带电粒子的赝快度分布

摘要

The pseudorapidity distribution function of charged particles in nucleon-nucleon collisions was presented.By using Glauber model, the mean numbers of participants, spectators in collision area, leading particles and binary nucleon-nucleon collisions were calculated.The pseudorapidity distributions of charged particles in nucleus-nucleus collisions are obtained.The theoretical results are consistent with those of the experimental observations in Au-Au collisions at (√-SNN) =130 GeV made by the PHOBOS collaboration.%给出了核子-核子碰撞末态带电粒子的赝快度分布函数,采用Glauber模型,计算出核-核碰撞过程中的平均参与者数、碰撞区域内的旁观者数、带头粒子数以及平均核子-核子碰撞数,获得了核-核碰撞的末态带电粒子的赝快度分布方程,与PHOBOS合作组√SNN=130 GeV的金-金碰撞末态带电粒子的赝快度分布的实验结果吻合.
