标题： Non-extensive statistics effects in quark-gluon plasma and in relativistic heavy-ion collisions

摘要： 在重离子碰撞初期多粒子系统中存在记忆效应和颜色长程力，这些因素可能会影响冻结温度下的粒子统计行为。在此背景下，我们采用广义非广延平衡热力学框架，计算了在中心 Pb+Pb 碰撞过程中发射的π介子的横向质量谱形状以及π介子的横向动量关联函数值，并表明假设与标准统计非常小的偏差即可很好地再现实验结果。 显示英文摘要

摘要： The presence of memory effects and color long-range forces among the many-parton system in the early stage of heavy-ion collisions can affect the particle statistical behavior at the freeze-out temperature. In this context, we calculate, in the framework of the equilibrium generalized non-extensive thermostatistics, the shape of pion transverse mass spectrum and the value of the transverse momentum correlation function of the pions emitted during the central Pb+Pb collisions and we show that the experimental results is well reproduced assuming very small deviations from the standard statistics.
