论文摘要
我们介绍了在横向动量依赖性（TMD）方法中，在$ e^+e^ - $ e nihilation过程中的两种二体生产的方位角依赖性和极化的完整结构。完全解释了Spin-1/2 Hadron的领先的TMD片段化函数（TMD-FFS）。还讨论了偏振FF的作用，以及从Belle数据中提取$λ$的横向极化的作用。最后，提出了EIC的SIDIS过程的预测。
We present the complete structure of the azimuthal dependences and polarization observables for two-hadron production in $e^+e^-$ annihilation processes within a transverse momentum dependent (TMD) approach adopting the helicity formalism. The leading-twist TMD fragmentation functions (TMD-FFs) for spin-1/2 hadrons are fully accounted for. The role of the polarizing FF, together with its extraction from Belle data for the transverse polarization of $Λ$'s, are discussed as well. Finally, predictions for SIDIS processes at EIC are presented.
