本文计算了强子碰撞中Drell-Yan轻子对产生中横动量加权单横自旋不对称性的次至首阶微扰QCD修正。我们确定的分裂函数相关的扭曲三夸克胶子相关函数的尺度演化。我们评论的后果，我们的结果现象学。
We calculate the next-to-leading order perturbative QCD corrections to the transverse momentum weighted single transverse spin asymmetry in Drell-Yan lepton pair production in hadronic collisions. We identify the splitting function relevant for the scale evolution of the twist-three quark-gluon correlation function. We comment on the consequences of our results for phenomenology.
