规范不变性在单自旋非对称性中的作用

The Role of Gauge Invariance in Single-Spin Asymmetries

C. J. Bomhof, P. J. Mulders

摘要:

我们认为,通过Wilson线,规范不变性使得强子散射过程中加权自旋不对称的硬函数由胶子极截面给出,而不是通常的部分子截面.

英文摘要:

We argue that through the Wilson lines, gauge invariance has as an effect that the hard functions in weighted spin-asymmetries in hadronic scattering processes are given by gluonic pole cross sections, rather than the usual partonic cross sections.
