摘要
利用Q Q色八重态产生机制 ,计算并讨论了色八重态对高能π -p碰撞过程的贡献 .发现 ,在大PT 时 ,色八重态的贡献不可忽略 ,甚至超过色单态的贡献 .计算结果与未来实验比较 。
In this paper, using the color-octet mechanism of Q, the cross section of high Energy π-p Collision process is calculated. We found that the color-octet contributions can not be neglected and are even larger than color-singlet contributions at high P T. Compared with the future experiments, the parton distribution functions that we have used and Q color-octet mechanism can be examined.
