论文摘要
基于通用的Parton分布（GPD）分解，在手袋方法中分析了独家$π^0 $电源。我们将领先的贡献与横向效应一起考虑。结果表明，在描述$π^0 $ cross部分的描述中，横向，$ h_t $和$ \ bar e_t $ gpds至关重要。对中国未来电子对撞机（EICC）能量范围的预测进行了预测。据发现，在低能量下观察到的横向优势$σ_T\ggσ_l$直至EICC能量范围。
The exclusive $π^0$ electroproduction is analyzed within the handbag approach based on Generalized Parton Distributions (GPDs) factorization. We consider the leading-twist contribution together with the transversity effects. It is shown that the transversity, $H_T$ and $\bar E_T$ GPDs are essential in the description of $π^0$ cross section. Predictions for future Electron-Ion Collider of China (EicC) energy range are done. It is found that transversity dominance $σ_T\ggσ_L$, observed at low energies is valid up to EicC energy range.
