Query: A model of diffractive excitation in $pp$ collisions at high energies   A phenomenological model for the description of the single and double
diffractive excitation in $pp$ 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 $\rho$ parameter and the differential
elastic cross section are also presented and shortcomings of the current model
are discussed.
