Abstract

The General Parton Distributions (GPDs) are applied to study the hard Pseudoscalar Meson Production (PMP) at high energies. The PMP amplitudes are be obtained within the GPDs factorization. They are expressed in terms of GPDs’ convolution functions, which are most essential in PMP reactions. We show that these convolution functions can be extracted from the PMP data in future EIC of China (EicC). Predictions of $\pi^{0}$ and $\eta$ production at typical EicC energies are performed.

从$${\pi}^{{0}}$和$$${\eta}$生产中提取中国EIC的横向GPD信息

摘要通用粒子分布（GPDs）被用于研究高能量下的硬伪谱介子产生（PMP）。在 GPDs 因式分解中可以得到 PMP 振幅。它们用 GPD 的卷积函数来表示，这在 PMP 反应中是最重要的。我们的研究表明，这些卷积函数可以在未来的中国电子集成电路（EICC）中从 PMP 数据中提取出来。我们还预测了在典型EicC能量下的$\pi^{0}$和$\eta$产生。
