Abstract
We study the small- evolution equation for the gluon generalized parton distribution (GPD) of the nucleon. It is shown that 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 gets saturated in the same way as its helicity-nonflip counterpart . Our result has a direct impact on the modeling of as well as the small- contribution to nucleon spin sum rules.
