  {In this paper we propose a new impact-parameter dependent CGC/saturation
model. We introduce two new features in the model that make it consistent with
what we know theoretically about the deep inelastic scattering. They are: the
use of the exact form of the solution to the non-linear (BK) equation, whereas
in all previous attempts only the form of $r^2Q^2_s$ dependence, has been taken
into account; and the large impact parameter dependence, through the
$b$-dependence of the saturation momentum which reproduce the correct behaviour
of the amplitude at large impact parameters $b$ ($A \propto \exp\Lb - \mu
b\Rb$) as well as at large momentum transferred $Q_T$ ($A $ decreases as a
power of $Q_T$ as it follows from perturbative QCD). These improvement compared
to all previous attempts to build such models, allows us to claim, that the
experimental data are in accord with the prediction of CGC/saturation approach
while previously, based on similar models, we could only conclude that the DIS
data, perhaps, can be described by introducing the shadowing corrections at
small photon virtualities.
