论文摘要
用P+P（$ \ rm \ overline {p} $）测量的带电颗粒的伪行为分布，从$ \ sqrt {s_ {nn}} = 23.6 $ GEV到13 tev，d+au colives in $ \ sqrt { $ \ sqrt {s_ {nn}} = 5.02 $ tev和rhic和LHC的A+A碰撞在使用Tsallis热力学的火球模型中进行了研究。我们假设速度轴是在Q高斯分布之后带有火球的填充，而带电的颗粒遵循火球中的Tsallis分布。理论结果与所研究的所有碰撞系统和中心的实验数据非常吻合。还研究了中央位置$ y_0 $及其宽度$σ$的碰撞能量和中心性依赖性。提出了该模型最近针对最近针对RHIC的Star实验提出的系统大小扫描程序预测带电粒子伪型分布的一种应用。
The pseudorapidity distributions of charged particles measured in p+p($\rm \overline{p}$) collisions for energies ranging from $\sqrt{s_{NN}}=23.6$ GeV to 13 TeV, d+Au collisions at $\sqrt{s_{NN}}=200$ GeV, p+Pb collisions at $\sqrt{s_{NN}}= 5.02$ TeV and A+A collisions at RHIC and LHC are investigated in the fireball model with Tsallis thermodynamics. We assume that the rapidity axis is populated with fireballs following q-Gaussian distribution and the charged particles follow the Tsallis distribution in the fireball. The theoretical results are in good agreement with the experimental data for all the collision systems and centralities investigated. The collision energy and centrality dependence of the central position $y_0$ and its width $σ$ of the fireball distribution are also investigated. A possible application of the model to predict the charged particle pseudorapidity distributions for the system size scan program proposed recently for the STAR experiment at RHIC is proposed.
