相对论性强子气体的正则配分函数
The canonical partition function for relativistic hadron gases
摘要：
高能碰撞中的粒子产生通常在热（统计）模型的框架内解决。本文给出了一种计算重子数、奇异性、电荷、粲数和底数精确守恒的强子共振气体的正则配分函数的方法。我们推导出一个解析表达式的配分函数表示为一系列的贝塞尔函数。我们的结果可直接用于分析基元碰撞和重离子碰撞中的粒子产生产额。我们还量化了量子统计在强子共振气体正则热模型中计算轻粒子多重数的重要性。
英文摘要：
Particle production in high-energy collisions is often addressed within the framework of the thermal (statistical) model. We present a method to calculate the canonical partition function for the hadron resonance gas with exact conservation of the baryon number, strangeness, electric charge, charmness and bottomness. We derive an analytical expression for the partition function which is represented as series of Bessel functions. Our results can be used directly to analyze particle production yields in elementary and in heavy ion collisions. We also quantify the importance of quantum statistics in the calculations of the light particle multiplicities in the canonical thermal model of the hadron resonance gas.
