摘要 利用相对论纵向非均匀集体膨胀流模型讨论RHIC能区的π介子分布,发现用此模型无法拟合π介子分布.作为改进,分别引入射弹和靶碎裂区的发射源,将π介子分布看成为射弹发射源、靶发射源和中心集体流3者贡献之和,以此理论得到的π介子分布与实验结果能较好地符合. We use longitudinally non-uniform collective expansion flow model to analyze the pion distribution at RHIC energy region. It is found that the projectile, target emitting source and central collective flow all contribute to the pion distribution. The results extracted from this theory are in good agreement with the experimental data.
