  We propose a new parton model and demonstrate that the model describes the
relevant experimental data at high energies. The model is based on Pomeron
calculus in 1+1 space-time dimensions, as suggested in Ref. [18] and on simple
assumptions regarding the hadron structure, related to the impact parameter
dependence of the scattering amplitude. This parton model evolves from QCD,
assuming that the unknown non-perturbative corrections lead to fixing size of
the interacting dipoles. The advantage of this approach is that it satisfies
both t-channel and s-channel unitarity, and can be used for summing all
diagrams of Pomeron interactions, including Pomeron loops. We can use this
approach for all reactions: dilute-dilute (hadron-hadron), dilute-dense
(hadron-nucleus) and dense-dense (nucleus-nucleus)for the scattering of parton
systems. Unfortunately, we are still far from being able to tackle this problem
in the effective QCD theory at high energy (i.e. in the CGC /saturation
approach).
