NICA能量下的公理化非广延统计

Axiomatic nonextensive statistics at NICA energies

Abdel Nasser Tawfik

摘要:

我们讨论了实施公理化的非广延统计的可能性,它是obtured相空间体积决定(非)广泛的熵,在NICA能量的粒子生产。玻尔兹曼-吉布斯和察利斯统计量都是这种一般(非)扩展性的非常特殊的情况。我们的结论是晶格热力学是{ \it ab initio}广延的和可加的,因此非广延的方法包括Tsallis统计分类与它们不匹配,而粒子产生,例如在不同质心能量下的粒子比,可能是一个非广延的过程,但肯定不是Tsallis类型。由此产生的冻结参数,温度和化学势,是近似兼容的从玻尔兹曼-吉布斯统计推断。

英文摘要:

We discuss the possibility of implementing axiomatic nonextensive statistics, where it is conjectured that the phase-space volume determines the (non)extensive entropy, on the particle production at NICA energies. Both Boltzmann-Gibbs and Tsallis statistics are very special cases of this generic (non)extensivity. We conclude that the lattice thermodynamics is {\it ab initio} extensive and additive and thus the nonextensive approaches including Tsallis statistics categorically are not matching with them, while the particle production, for instance the particle ratios at various center-of-mass energies, is likely a nonextensive process but certainly not of Tsallis type. The resulting freezeout parameters, the temperature and the chemical potentials, are approximately compatible with the ones deduced from Boltzmann-Gibbs statistics.
