  Higher order corrections to the Balitsky-Kovchegov equation have been
estimated by introducing a rapidity veto which forbids subsequent emissions to
be very close in rapidity and is known to mimic higher order corrections to the
linear BFKL equation. The rapidity veto constraint has been first introduced
using analytical arguments obtaining a power growth with energy, Q_s (Y) ~
exp(lambda Y), of the saturation scale of lambda ~ 0.45. Then a numerical
analysis for the non-linear Balitsky-Kovchegov equation has been carried out
for phenomenological rapidities: when a veto of about two units of rapidity is
introduced for a fixed value of the coupling constant of alpha_s = 0.2 the
saturation scale lambda decreases from ~ 0.6 to ~ 0.3, and when running
coupling effects are taken into account it decreases from ~ 0.4 to ~ 0.3.
