标题： Particle production in relativistic $pp$($\overline{p}$) and $AA$ collisions at RHIC and LHC energies with Tsallis statistics using the two-cylindrical multisource thermal model

摘要： 在多源热模型中实施了改进的塔尔萨斯统计，以系统地描述在不同碰撞能量下相对论性核-核（$AA$）碰撞以及相对论性核子-核子（$pp$或$p\overline{p}$）碰撞中产生的赝快度谱。 使用双圆柱多源热模型的塔尔萨斯统计结果与RHIC和LHC能量下测得的实验数据吻合良好。 发现纵向源的赝快度偏移随着框架中的碰撞能量和中心度线性增加。 根据这些规律，我们还预测了更高能量下的$pp$（$\overline{p}$）碰撞的赝快度分布。 显示英文摘要

摘要： An improved Tsallis statistics is implemented in a multisource thermal model to describe systematically pseudorapidity spectra of charged particles produced in relativistic nucleon-nucleon ($pp$ or $p\overline{p}$) collisions at various collision energies and in relativistic nucleus-nucleus ($AA$) collisions at different energies with different centralities. The results with Tsallis statistics using the two-cylindrical multisource thermal model are in good agreement with the experimental data measured at RHIC and LHC energies. It is found that the rapidity shifts of longitudinal sources increase linearly with collision energies and centralities in the framework. According to the laws, we also give a prediction of the pseudorapidity distributions in $pp$($\overline{p}$) collisions at higher energies.
