在2+1维经典Yang-Mills理论框架下,数值研究了相对论重离子碰撞的初始阶段。我们计算了产生的胶子的能量密度、数密度和动量谱。该模型也适用于非中心碰撞。根据RHIC的能量和多重数测量以及其他理论计算,对数值结果进行了讨论。指出了现有方法存在的一些问题。
The initial stages of relativistic heavy ion collisions are studied numerically in the framework of a 2+1 dimensional classical Yang-Mills theory. We calculate the energy and number densities and momentum spectra of the produced gluons. The model is also applied to non central collisions. The numerical results are discussed in the light of RHIC measurements of energy and multiplicity and other theoretical calculations. Some problems of the present approach are pointed out.
