利用基于PYTHIA模型的部分子和强子级联模型PACIAE，系统地分析了LHC能区（s= 0.9，2.36和7TeV）p+p碰撞的ALICE，CMS和ATLAS测量结果.我们强调的影响，部分子再散射的实验数据的分析比较PACIAE的结果（与部分子再散射）的PYTHIA的（没有部分子再散射）。结果表明，初始火球中的部分子再散射对理解实验数据有一定的作用，且部分子再散射效应随反应能量的增加而增强。
ALICE, CMS, and ATLAS measurements for p+p collisions at LHC energies (s=0.9, 2.36, and 7 TeV) are analyzed systematically using the parton and hadron cascade model PACIAE which is based on the PYTHIA model. We emphasize the impact of parton rescattering on the analysis of experimental data by comparing the PACIAE results (with parton rescattering) to the PYTHIA ones (without parton rescattering). It turned out that the parton rescattering in the initial fireball plays an role in understanding the experimental data and the parton rescattering effect increases with the reaction energy increasing.
