Abstract

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 Q s ( Y ) and verify that Q s ( Y = c s t e ) scales as max ( q , Q T ) , where Q T is the scale caracterizing the target.
