Geometric scaling in high-energy QCD at nonzero momentum transfer
G. Soyez, C. Marquet, R. Peschanski
Abstract
We show how one can obtain geometric scaling properties from the Balitsky-Kovchegov (BK) equation. We start by explaining how, this property arises for the b-independent BK equation. We show that it is possible to extend this model to the full BK equation including momentum transfer. The saturation scale behaves like max(q,QT) where q is the momentum transfer and QT a typical scale of the target.
