摘要
通过研究随机级联α模型,证明了对于固定的动力学起伏强度,多粒子末态相空问有间歇现象,但是没有混沌现象.只有当不同事件的动力学起伏强度不同时才能同时观察到多粒子末态的间歇与混沌行为.这说明,在高能碰撞中,分形与混沌是两个相互联系但又不同的非线性动力学性质.
it is shown that an event sample from the Monte Carlo simulation ofa random cascading α model with fixed dynamical fiuctuation strength isintermittent but not chaotic, while the variance of dynamical fluctuation strengthin different events will result in both the intermittency and the chaohcity behavior.This shows that fractality and chaoticity are two connected but different featuresof non-linear dynamics in high energy collisions.
