摘要 粒子横动量谱能反映强相互作用介质中强子化过程中的诸多信息.通过考虑末态随动者对J/Ψ粒子产额的影响和初态核子-核子碰撞几何分布对J/Ψ粒子分布的影响,利用传统爆炸波模型,对RHIC能区Au-Au、Cu-Cu的中心快度区间和向前快度区间的J/Ψ粒子横动量谱进行了讨论. The transverse momentum spectrum of particles contain valuable information of the hadronization process in the strongly interacting medium. We advocate the comovers will change the yield of final J/Ψ mesons; and the distribution of binary nucleon-nucleon collisions will determine the distribution of J/Ψ mesons; and the transverse momentum spectrum of J/Ψ mesons measured at the RHIC can be analyzed well by our modified blast-wave model.
