标题： On Dynamics of Fractality in Central C-Cu Collisions at 4.5A Gev/c

摘要： 通过间歇性方法和多重分形分析研究了在 4.5A GeV/c 束流能量下 C-Cu 中心碰撞中电荷粒子在伪快度和横向动量上的分形结构。 修正以考虑统计偏差的方法被应用。 伪快度相空间中的间歇性研究表明存在非热相变以及多粒子产生的不同阶段。 两种方法均观察到了多重分形特性。 研究了使用有效平均多重数方法的两种方法之间的相互关系。 研究结果支持有限多重数影响具有统计显著性的观点。 在横向动量谱中未发现动力学涨落。 显示英文摘要

摘要： Fractal structure of charged particle distributions in the pseudorapidity and transverse momentum in central C-Cu collisions at 4.5A GeV/c is studied by means of intermittency approach and multifractal analysis. The modifications to take into account statistical bias are applied. Intermittency study in the pseudorapidity phase space indicates a non-thermal phase transition and different regimes of multiparticle production. Multifractality is observed within the both methods applied. The interrelation of the methods using the effective average multiplicity approach is studied. The findings support the idea of statistical significance of influence of finite multiplicities. In the transverse momentum spectrum no dynamical fluctuations are found.
