| 摘 要： | 核-核碰撞可以简单看成核子-核子碰撞,每一核子-核子碰撞产生的源可用经典流表示。对于时空函数的经典流系综,当源部分相干时,全同两粒子玻色-爱因斯坦关联函数公式应包含混沌和相干项。根据蒙特卡罗的模拟计算思想,由混沌源2π关联函数的模拟计算出发,得到部分相干源关联函数的模拟计算方法。在相对动量q的out和side方向上,对部分相干源关联函数进行蒙特卡罗模拟计算,计算得到源的半径Rout在误差范围内近似等于Rside。

| Abstract: | Nucleus-nucleus collisions are simply regarded as sum of nucleon-nucleon collisions.Particle sources produced by nucleon-nucleon collisions are treated as classical current.For the classical current formalism ensemble of space-time function there are two terms in two identical particle Bose-Einstein correlation function when sources are partially coherent and one is called coherent term,the other is chaotic one.According to Monte Carlo simulating theory,the algorithm for calculating correlation function of ... |
