摘要
用蒙特卡罗模型研究了相对论重离子碰撞中逐事件横动量起伏与多重数的关联,发现蒙特卡罗产生器HIJING不能描述实验现象.提出了一个简单的蒙特卡罗模型,可以与实验一致,有助于理解逐事件横动量起伏与多重数关联的动力学起源.
The experimental observation on the multiplicity dependence of event-by-event transverse momentum fluctuation in relativistic heavy ion collisions is studied using Monte Carlo simulation. It is found that the Monte Carlo generator HIJING is unable to describe the experimental phenomenon well. A simple Monte Carlo model is proposed, which can recover the data and thus shed some light on the dynamical origin of the multiplicity dependence of event-by-event transverse momentum fluctuation.
