摘要
A study of the dynamical fluctuation properties at various c.m. energies in e^＋e^- collisions is performed using the Monte Carlo method. The results suggest that, after the normalized factorial moments of 3-dimensional phase space are analyzed using an isotropical phase space partition, the NFM describing non- linear dynamical properties show a power-law scaling, i.e., the dynamical fluctuations in higher dimensional phase space are isotropic. For c.m. energies √s≤ 80 GeV, the scaling exponents φq increase rapidly with the c.m. energy and for c.m. energies √s 〉 80 GeV, the φq gradually saturate.
