Analysis of differential cross sections of the TOTEM Collaboration data, carried out without model assumptions, shows the existence of new effects in the behavior of the hadron scattering amplitude at a small momentum transfer at a high confidence level. The quantitative description of the data in the framework of the high energy generalized structure (HEGS) model supports such a phenomenon that can be associated with the specific properties of the hadron potential at large distances. It is shown that the value of ρ(s, t) at √ s = 13 TeV and small t exceeded 0.1.

“…In the framework of the model the description of experimental data was obtained simultaniously at the large momentum transfer and in the Coulomb-hadron region in the energy region from √ s = 9 GeV up to LHC energies with taking into account the Coulomb-nuclear phase [29,30]. The model gives a very good quantitative description of recent experimental data at √ s = 13 TeV [31].…”

Taking into account the PDFs, obtained by different Collaborations, the momentum transfer dependence of GPDs of the nucleons is obtained. The calculated electromagnetic and gravitomagnetic form factors of nucleons are used for the description of different form factors and the nucleons elastic scattering in a wide energy and momentum transfer region with a minimum number of fitting parameters. The electromagnetic and gravitomagnetic radii of the nucleon are calculated using the obtained momentum transfer dependence of GPDs with different forms of PDFs obtained by different Collaborations. The comparison of the calculations, taking into account the PDFs obtained by different Collaborations, of mean square electromagnetic and gravitomagnetic radii of nucleons is made.

“…At large t our model calculations are extended up to −t = 15 GeV 2 . We added a small contribution of the energy independent part of the spin flip amplitude in the form similar to the proposed in 13 and analyzed in 14 . The model is very simple from the viewpoint of the number of fitting parameters and functions.…”

The dependence of the hadron interaction on its structure is examined in the framework of the generelized parton distributions (GPDs). The x dependence of the GPDs is determined by the parton distribution functions (PDFs), which were obtained from the deep inelastic scattering. The analysis of the whole sets of experimental data on the electromagnetic form factors of the proton and neutron with taking into account many forms of PDFs, obtained by the different Collaborations, make it possible to obtain the special momentum transfer dependence of the GPDs. This permits us to obtain the electromagnetic and gravitomagnetic form factors of the nucleons. The impact parameter dependence of the proton and neutron charge and matter densities is examined. The elastic hadron scattering at high energies was analyzed in the framework of the model that takes into account both these form factors (electromagnetic and gravitomagnetic).
