质心能量为23.6 ~ 900 GeV的p-p碰撞中产生的带电粒子的赝快度分布

The pseudorapidity distributions of the produced charged particles in p-p collisions at center-of-mass energies from 23.6 to 900 GeV

摘要:

在p-p碰撞中,有两个主导粒子。一个是弹丸破碎区。另一种是在靶向碎裂区。本文的研究表明,与核-核碰撞一样,修正的Landau流体动力学模型不足以很好地描述p-p碰撞中产生的带电粒子的赝快度分布。只有在考虑了先导粒子的影响后,实验数据才能得到较好的拟合。理论模型在sqrt(sNN)=23.6 ~ 900 GeV的整个可用能量范围内对p-p碰撞都适用。

英文摘要:

In p-p collisions, there are two leading particles. One is in projectile fragmentation region. The other is in target fragmentation region. The investigations of present paper show that, just like in nucleus-nucleus collisions, the revised Landau hydrodynamic model alone is not enough to have a good description to the measured pseudorapidity distributions of the produced charged particles in p-p collisions. Only after the leading particles are taken into account as well, can the experimental data be matched up properly. The theoretical model works well in p-p collisions in the whole available energy region from sqrt(s_NN) =23.6 to 900 GeV.
