论文摘要
众所周知，在半包含的深度非弹性散射中，单个横向自旋不对称可以通过扭曲3分布函数$ t_f $进行分解，$ t_f $，其中包含gluon场强度张量。在功率扩展中包含横向GLUON的情况下，我们发现Gluon场强量张量可以肯定地以$α_s$膨胀的领先顺序以软脱云的贡献来恢复。这个结论在Feynman和Light-Cone仪表中得以实现。
It is known the single transverse spin asymmetry in semi-inclusive deep inelastic scattering can be factorized by a twist-3 distribution function $T_F$, which contains a gluon field strength tensor. With transverse gluon included in the power expansion, we find the gluon field strength tensor can be recovered definitely in soft-gluon-pole contribution at leading order of $α_s$ expansion. This conclusion holds in Feynman and light-cone gauges.
