摘要

我们通过假设夸克在横向和纵向空间中的电荷-同位旋对称，对低洼八元重子成员进行了结构分析。利用光锥观察者双夸克模型，我们研究了八元重子的电磁形状因子，并与现有数据进行了比较。对八元重子间非零偏度的PDFs和广义部分子分布（GPDs）进行了比较分析。利用深虚康普顿散射振幅关于偏度的傅里叶变换，进一步研究了升压不变纵向位置空间中的衍射图样。

Generalized parton distributions for low-lying octet baryons with non-zero skewness

We have performed the structural analysis of low-lying octet baryon members by assuming charge-isospin symmetry among quark flavors in transverse and longitudinal space. Using the light-cone spectator diquark model, we have investigated the electromagnetic form factors of the octet baryons and have compared them with the available data. A comparative analysis of PDFs and generalized parton distributions (GPDs) for non-zero skewness among octet baryons has also been demonstrated. Fourier transform of the deeply virtual Compton scattering amplitude with respect to skewness has been further applied to study the diffraction patterns in the boost-invariant longitudinal position space.
