胶子凝聚的部分子分布函数

Parton distribution function for the gluon condensate

Yoshitaka Hatta, Yong Zhao

摘要:

基于用光锥分布来理解核子质量结构的愿望,我们引入了一阶矩为核子中胶子凝聚的扭四部分子分布函数$F(x)$。我们提出了$F(x)$的运动关系方程,并讨论了δ函数(“零模”)在$x=0$的贡献的可能存在。我们还对夸克和胶子目标进行了单圈计算。

英文摘要:

Motivated by the desire to understand the nucleon mass structure in terms of light-cone distributions, we introduce the twist-four parton distribution function $F(x)$ whose first moment is the gluon condensate in the nucleon. We present the equation of motion relations for $F(x)$ and discuss the possible existence of the delta function (`zero mode') contribution at $x=0$. We also perform one-loop calculations for quark and gluon targets.
