| 摘 要： | 提出了一种相对论重离子碰撞中强子物质生成时的π膨胀源模型. 得到了该模型中的小相对论动量区域的2π关联函数及表观π源参数Ra与实际π源参数Re的关系. 这一关系与QGP生成时的关系有所区别. 这一区别可以用来检测相对论重离子碰撞中产生的非静态球形夸克-胶子等离子体的存在性. 两个关系也显示了一种标度行为.

| Abstract: | A model of expanding pion sources in relativistic heavy ion collisions,when only hadronic matter is generated,is proposed.The two-pion correlation function at small relative momentum for such a model is obtained with two-pion interferometry at small relative momentum,and the relation between the real spatial parameter Re and the apparent spatial parameter R_a of the pion sources is given.The relation is different from the one when QGP is created.The difference can be used to test nonstatic,spherical quark-gluon plasma produced in relativistic heavy ion collisions.The relation also showes a scaling behavior. |
