The Balitsky-Kovchegov equation in full momentum space

We analyse the Balitsky-Kovchegov (BK) saturation equation in momentum space and solve it numerically. We confirm that, in the limit where the transverse momentum of the incident particle k is much bigger than the momentum transfer q, the equation admits traveling-wave solutions. We extract the q dependence of the saturation scale Qs(Y) and verify that Qs(Y=cste) scales as max(q,QT), where QT is the scale caracterizing the target.
