Wei Zhu, Zhenqi Shen, Jianhong Ruan
TL;DR
This paper investigates a modified BFKL equation incorporating gluon fusion corrections, revealing a stronger shadowing effect that suppresses gluon density and suggests potential chaotic behavior at small x.
Contribution
It introduces a unified partonic framework with a new correction to the BFKL equation, predicting novel gluon saturation phenomena and possible chaos.
Findings
Stronger shadowing effect suppresses gluon density at small x.
Gluon disappearance predicted below saturation.
Potential chaotic solutions of the modified equation.
Abstract
The corrections of the gluon fusion to the BFKL equation in a unified partonic framework are studied. This modified BFKL equation predicts a stronger shadowing, which suppresses the gluon density and even leads to the gluon disappearance below the saturation region. We suggest that this unexpected effect is caused by a possible chaotic solution of the new equation.
