Sources of event-by-event elliptic flow fluctuations in relativistic heavy-ion collisions are investigated in a multiphase parton transport model (AMPT). Besides the well-known initial eccentricity fluctuations, several other sources of elliptic flow dynamical fluctuations are identified. One is fluctuations in initial parton configurations at a given eccentricity. Configuration fluctuations are found to be as important as eccentricity fluctuations in elliptic flow development. A second is quantum fluctuations in parton-parton interactions during system evolution. A third is fluctuations cause...

event-by-event 的来源在相对论的重离子的碰撞的椭圆形的流动变化在一个多相的 parton 运输模型(AMPT ) 被调查。除著名起始的怪癖变化以外，几其它椭圆形的流动采购原料动态变化被识别。一个人是在在一个给定的怪癖的起始的 parton 配置的变化。配置变化被发现象在椭圆形的流动开发的怪癖变化一样重要。一秒在系统进化期间是在 parton-parton 相互作用的量变化。第三是 hadronization 和最后状态的 hadronic 散布引起的变化。这些变化的大小相对怪癖变化和平均椭圆形的流动大小被调查。从二来源被发现否定的后者的变化。结果可以为椭圆形的流动数据的解释有重要含意。
