论文摘要

我们研究了从光前的QCD Hamiltonian中使用一个动力学的​​光中膜的结构,该结构是根据其组成的夸克 - 易夸克(Quark-Antiquark)和夸克 - 易夸克 - 格鲁恩(Quark-Antiquark-Gluon)群的组成部分,以及三维的限制。拟合光介子质谱法后,光线波函数可提供质量的质量描述,并在QCD尺度演化后的价夸克分布函数。

We investigate the structure of the light meson with one dynamical gluon from the light-front QCD Hamiltonian, determined for their constituent quark-antiquark and quark-antiquark-gluon Fock sectors, together with a three-dimensional confinement. After fitting the light meson mass spectroscopy, the light-front wave functions provide a good quality description of the pion electromagnetic form factor, and the valence quark distribution functions following QCD scale evolution.
