In this paper we consider the Good -Walker approach for the diffractive excitation and updated the Miettinen -Pumplin (MP) model for pp/pp collisions considering the recent LHC data for the total and elastic pp cross sections. The behavior of the total, elastic and diffractive cross sections is analyzed and predictions for the energies of Run 3 of the LHC and those of the Cosmic Rays experiments are derived. Our results demonstrate that the MP model is able to describe the current data and that it implies that the cross section for the diffraction excitation in pp collisions is almost constant in the energy range probed by the LHC and slowly decreases at higher energies. Our results indicate that the Pumplin bound is not reached at the LHC and Cosmic Ray energies. Moreover, the implications of the diffractive excitation in pA collisions is discussed. In particular, the MP model, constrained by the pp data, is used to derive the main quantities present in the treatment of the diffractive excitation in pA collisions. Predictions for the total, elastic and diffractive pA cross sections are presented considering different nuclei. We demonstrate that the effect of fluctuations decreases at larger energies and heavier nuclei. The energy dependence of the diffractive excitation cross section in pA collisions is estimated for different nuclei and compared with the predictions for the proton dissociation induced by photon interactions.

“…Our data set comprise data only from accelerator experiments and covers the energy range from 5 GeV to 13 TeV. Data below 1.8 TeV were obtained from the Particle Data Group [18], while for the LHC energies, we included data obtained by TOTEM Collaboration in the energies of 2.76, 7, 8 and 13 TeV [19][20][21][22][23][24] and data by ATLAS Collaboration at 7 and 8 TeV [25,26]. For all data, we considered statistical and systematical uncertainties added in quadrature.…”

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 ρ parameter and the differential elastic cross section are also presented and shortcomings of the current model are discussed.

The analysis on the hadron-hadron scattering at high energies in the framework of holographic QCD is presented. Combining the Pomeron exchange kernel and the hadron-Pomeron couplings which are obtained from the bottom-up AdS/QCD models, we calculate the total cross sections. Our calculation for the nucleon-nucleon scattering is consistent with the experimental data including the recent ones measured by the TOTEM collaboration at the LHC. Within the framework, one can consider other processes involving other hadrons. As examples to show this feature of the model, the resulting total cross sections of the pion-nucleon and pion-pion scattering are also presented.
