标题： Intercepts of the momentum correlation functions in μ-Bose gas model and their asymptotics

摘要： 所谓的\mu -变形振子（或\mu -振子）由A.Jannussis引入，虽然相对于其他更著名的变形振子模型具有相当奇特的性质，但也具有广泛物理应用的良好潜力。 在本文中，基于\mu -振子的相应\mu -玻色气体模型被探讨。 在这个模型中，计算了两粒子和三粒子动量关联函数的截距\lambda ^(2)(K) 和\lambda ^(3)(K)，目的是可能用于模拟相对论重离子碰撞实验中观察到的两介子和三介子关联截距的非玻色型行为。 在推导截距时，考虑了变形参数\mu 的不同阶次近似。 我们的分析还给出了截距\lambda ^(2)(K) 和\lambda ^(3)(K) 的渐近行为。 结果对于\lambda ^(2)(K) 与实验数据以及使用其他变形玻色气体模型得出的早期已知结果进行了比较。 显示英文摘要

摘要： The so-called \mu-deformed oscillator (or \mu-oscillator) introduced by A.Jannussis, though possesses rather exotic properties with respect to other better known deformed oscillator models, also has good potential for diverse physical applications. In this paper, the corresponding \mu-Bose gas model based on \mu-oscillators is explored. Within this model, the intercepts \lambda^(2)(K) and \lambda^(3)(K) of two- and three-particle momentum correlation functions are calculated with the goal of possible application for modeling the non-Bose type behavior of the intercepts of two- and three-pion correlations, observed in the experiments on relativistic heavy ion collisions. In derivation of intercepts, different orders of approximation in the deformation parameter \mu are considered. Our analysis also yields asymptotical behavior of the intercepts \lambda^(2)(K) and \lambda^(3)(K). The results for \lambda^(2)(K) are compared with experimental data, and with earlier known results drawn using other deformed Bose gas models.
