RHIC能区粒子分布特征与中心度关系的研究

摘要

Gluon saturation model realized that the gluon saturation feature might be presented with the increasing of collision energy of relativistic heavy-ion, and calculated the saturated gluon distributions. The gluon saturation model has been developed and combined the gluon saturation model with hydrodynamic space- time evolution to study the dependence of centrality on multiplicity distribution at Retativistic Heavy Ion Collider.%胶子饱和模型认为:随着高能重离子碰撞能量的升高,会出现胶子饱和现象,并给出了饱和胶子分布.进一步发展了胶子饱和模型,将胶子饱和与流体动力学时空演化结合起来,系统分析RHIC能区的粒子分布随中心度的变化关系.
