Drell-Yan过程中单横自旋不对称性的次领先级计算

Next-to-leading Order Calculation of the Single Transverse Spin Asymmetry in the Drell-Yan Process

Werner Vogelsang, Feng Yuan

摘要:

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。我们确定了与扭曲三夸克胶子关联函数的尺度演化有关的分裂函数。我们评论的后果,我们的结果现象学。

英文摘要:

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.
