论文摘要

我们从轻量量子染色体动力学(QCD)有效的哈密顿量求解了核子的光线波函数,并具有三维限制。我们使用三个夸克与三个夸克和一个Gluon Fock组件相结合的组成部分获得解决方案。所得的光额波函数可在QCD量表演化后对核子的夸克分布函数提供良好的质量描述。我们介绍了构成构成核子自旋总和规则的核子的Gluon密度,螺旋分布和轨道角动量的影响。

We solve for the light-front wave functions of the nucleon from a light-front quantum chromodynamics (QCD) effective Hamiltonian with three-dimensional confinement. We obtain solutions using constituent three quarks combined with three quarks and one gluon Fock components. The resulting light-front wave functions provide a good quality description of the nucleon's quark distribution functions following QCD scale evolution. We present the effects from incorporating a dynamical gluon on the nucleon's gluon densities, helicity distribution and orbital angular momentum that constitutes the nucleon spin sum rule.
