A new perspective on gluon distribution at small x

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.

Comments: This paper has been withdrawn by the author due to the input Eq. (4.7) is incorrect and all results Fig. 13-20 need reconsideration
