论文摘要
我们研究质子在基础光 - 前量化（BLFQ）框架内的动量空间和位置空间中质子的价值夸克的质量夸克（BLFQ）框架中质子的价依赖性和螺旋依赖性的广义Parton分布（GPD）。价值夸克的GPD是从价值范围的轻率有效哈密顿式扇区中的特征向量计算出来的，该速率由三维限制潜力和与固定耦合的单连体交换相互作用组成。使用这些GPD，我们获得了质子内部夸克角动量的空间分布。在我们的BLFQ方法中，我们探讨了角动量密度的各种定义，并说明了它们是由整合到零的术语产生的差异。我们还讨论了对夸克角动量密度的风味贡献。
We study the unpolarized and the helicity dependent generalized parton distributions (GPDs) for the valence quarks of the proton in both momentum space and position space within the basis light-front quantization (BLFQ) framework. The GPDs for the valence quarks are computed from the eigenvectors of a light-front effective Hamiltonian in the valence Fock sector consisting of a three-dimensional confinement potential and a one-gluon exchange interaction with fixed coupling. Employing these GPDs, we obtain the spatial distributions of quark angular momentum inside the proton. In our BLFQ approach, we explore various definitions of angular momentum density and illustrate the differences between them arising from terms that integrate to zero. We also discuss the flavor contributions to the quark angular momentum densities.
