摘要 在微扰 QCDαs近似下 ,采用双重 Q2 -重标度模型 ,计算了 αs 级 QCD修正对 P-A( 1 26 C,402 0 Ca,5 6 2 6 Fe)碰撞 Drell-Yan过程微分截面的贡献 .说明了对于核 Drell-Yan过程截面的计算 。 Taking into account perturbative QCD α s order approximation,using double Q 2 rescaling model,the contribution of QCD corrections of the cross section in P A( 12 6C, 40 20 Ca, 56 26 Fe)collision Drell Yan process are discussed.It is shown that the QCD corrections are not ignored.
