巨正则系综中强子气体范德华模型的粒子间吸引力
Attractive inter-particle force in Van der Waals model of hadron gas in the grand canonical ensemble
摘要：
本文将用硬核势推导相互作用粒子的多组分范德华气体巨正则系综的配分函数的方法推广到引力大距离平均场的情形。对于核物质中的中子、质子等不同气体组分，在透明的非相对论极限下，用鞍点方法得到的热力学势公式，可用于分析高激发能核-核碰撞中粒子数比的实验数据。
英文摘要：
We generalize derivation of partition functions of the grand canonical ensemble for the multicomponent van der Waals gas of interacting particles by hardcore potentials to the case of the attractive large-distance mean field. The formulas obtained by the saddle point method for the thermodynamic potentials with the transparent non-relativistic limit to the case of conserving large number of particles for different gas components like neutrons and protons of nuclear matter can be used for analysis of experimental data for the particle number ratios in nucleus-nucleus collisions at high excitation energies.
