在基光阵面量子化下含一个动力学胶子的轻介子

Light mesons with one dynamical gluon within basis light-front quantization

Jiangshan Lan, Kaiyu Fu, Chandan Mondal, Xingbo Zhao, James P. Vary

摘要:

我们研究了由夸克-反夸克和夸克-反夸克-胶子Fock扇区确定的光锋QCD哈密顿量和三维禁闭条件下含一个动力学胶子的轻介子的结构。通过对轻介子质谱的拟合,得到的光阵面波函数能很好地描述π介子的电磁形状因子和QCD标度演化后的价夸克分布函数.

英文摘要:

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.
