经典和量子Tsallis强子横动量谱的解析结果:零级近似及其以外

Analytical Results for the Classical and Quantum Tsallis Hadron Transverse Momentum Spectra: the Zeroth Order Approximation and beyond

Trambak Bhattacharyya, Alexandru S. Parvan

摘要:

本文导出了由Tsallis归一化(Tsallis-1)统计量得到的强子横动量谱中一阶和二阶项的解析表达式。我们重新讨论了零阶量子Tsallis分布,并得到了相应的解析封闭形式表达式。结果表明,与经典情形不同,零阶量子谱的解析封闭形式与文献中所用的$q \to q^{-1}$(其中$q$是Tsallis熵参数)代入后的唯象分布不相似.然而,因子分解近似增加了相似性的程度。

英文摘要:

We derive the analytical expressions for the first and second order terms in the hadronic transverse momentum spectra obtained from the Tsallis normalized (Tsallis-1) statistics. We revisit the zeroth order quantum Tsallis distributions and obtain the corresponding analytical closed form expressions. It is observed that unlike the classical case, the analytical closed forms of the zeroth order quantum spectra do not resemble the phenomenological distributions used in the literature after $q \to q^{-1}$ substitution, where $q$ is the Tsallis entropic parameter. However, the factorization approximation increases the extent of similarity.
