论文摘要
在原型分解程序中,我们研究了强子产生的核子 - 莱普顿硬核过程中表现出的gluon极的贡献。我们证明了Gluon Pole在这种过程中的主要作用。我们分析了与Gluon Pole函数相关的复杂性的不同来源。作为一种实际应用,我们得出了一种与Gluon杆直接相关的新单个自旋不对称,可以通过实验研究。
Within the archetypal factorization procedure, we study the gluon pole contributions manifesting in the nucleon-lepton hard processes of hadron production. We prove the dominant role of gluon pole contributions in the processes of such kind. We analyse the different sources of complexity associated with the gluon pole functions. As a practical application, we derive a new single spin asymmetry related directly to the gluon poles which can be studied experimentally.
