The Nonconstant of the K-factor in the Drell Yan Process of the Nuclei C -C Collision
摘要/Abstract
在 Drell-Yan过程中计入湮灭项和康普顿散射项的贡献, 利用双重 Q2 -重标度模型, 计算了碳核与碳核碰撞在给定不同的 x A1 值时 K因子随 x A2 的变化.结果表明, 对应不同的 x A1 值, K因子随 x A2 的变化曲线形状很不相同.计算结果与实验对照可以检验所用核效应的模型及 QCD理论.
In this paper, we have use the model of double Q2-rescaling to caluclate the change of K- factor with xA2change when the nuclei C-C is in collision which have been given different xA1on the va- lence, and in this calculation we have considered the contributions of annihilations and Compton Scatter- ing in the Drell-Yan process. The results show that the curve of K-factor with xA2is very different for different valence xA1. The calculating results are compared with exprimental data,it can not only test the model of its nuclear effect, but also the QCD theory.
