论文摘要
我们研究了核子的Gluon通用Parton分布（GPD）$ e_g $的小$ x $进化方程。结果表明，尽管它与Nucleon Helicity-Flip工艺相关，但消失的偏度偏斜行为与BFKL Pomeron相同。我们还考虑了Gluon饱和的效果，并证明了$ E_G $与其螺旋 - 非flip $ h_g $相同的方式饱和。我们的结果对$ e_g $的建模以及对Nucleon Spin Sum规则的小$ x $贡献产生了直接影响。
We study the small-$x$ evolution equation for the gluon generalized parton distribution (GPD) $E_g$ of the nucleon. It is shown that $E_g$ at vanishing skewness exhibits the Regge behavior identical to the BFKL Pomeron, despite its association with nucleon helicity-flip processes. We also consider the effect of gluon saturation and demonstrate that $E_g$ gets saturated in the same way as its helicity-nonflip counterpart $H_g$. Our result has a direct impact on the modeling of $E_g$ as well as the small-$x$ contribution to nucleon spin sum rules.
