一种典型Drell-Yan过程的理论研究

THE THEORETICAL RESEARCH OF A KIND OF DRELL—YAN PROCESS

在组分夸克模型的框架内，提出了核－核碰撞Ｄｒｅｌｌ－ Ｙａｎ 过程的计算方法。计算了Ｏ＋ Ｕ→μ＋ μ－ ＋ Ｘ的核效应并对结果进行了讨论，指出该过程的核效应来源于Ｏ核和Ｕ核三种核效应的综合作用。

Using the constituent-quark model,a calculating method of Drell-Yan process in nuclear nuclear collision is put forward.The nuclear effect in O+U→μ +μ -+X Drell-Yan process is calculated and the discussion shows that the nuclear effect of this process stems from the unified action of three kinds of nuclear effect in O nuclear and U nuclear.
