A phenomenological model for the description of the single and double diffractive excitation in p p collisions at high energies is presented. Considering the Good-Walker approach, we propose a model for the eigenstates of the scattering operator and for the treatment of the interaction between them, with the high energy behavior of the cross section driven by perturbative QCD. The behavior of the total, elastic, single, and double diffractive cross sections are analyzed and predictions for the energies of Run 3 of the LHC and those of the cosmic rays experiments are derived. We demonstrate that the model describes the current data for the energy dependence of the cross sections. A comparison with the recent data for the ρ parameter and the differential elastic cross section are also presented and shortcomings of the current model are discussed.
