The Contribution of QCD Corrections to the Cross Section in P-A Collision Drell-Yan Process
摘要/Abstract
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, QCD修正是不容忽略的
Abstract:
Taking into account perturbative QCDTs-order approximation, using double Q2 rescaling model, the contribution of QCD corrections of the cross section in P-A( 126C, 4020Ca, 5626Fe) collision Drell-Yan process are discussed. It is shown that the QCD corrections are not ignored.
