摘要
在2π干涉学中,对不同的π源,2π关联函数可以是不同的．如果在相对论重离子碰撞中出现柱形夸克胶 子等离子体,π介子将从柱形夸克胶子等离子体表面发射,此时2π关联函数将出现一种特殊的振荡行为．这种振 荡行为可以用来探明夸克胶子等离子体的存在性,同时也是相对论重离子碰撞中出现夸克胶子等离子体的一个 信号。
The two-pion correlation functions are different for some pion source distributions in two-pion interferometry. If quark-gluon plasma of cylindrical shape is produced in relativistic heavy ion collisions, the pion mesons will emit from the surface of quark-gluon plasma of cylindrical shape and the corresponding correlation function will have a special oscillation behavior. The oscillation behavior can be used to verify the existence of quark-gluon plasma and is also a signature of the appearance of quark-gluon plasma.
