Abstract
A simultaneous description of different spin independent and spin dependent reactions of nucleon–nucleon elastic scattering is obtained for all existing experimental data at low \(\sqrt{s}\geq 3.6\) GeV and high energies up to the last LHC energy. From the point of view of the generalized parton structure of hadrons which unifies parton distributions of the proton, neutron, antiproton and meson the corresponding electromagnetic and gravitomagnetic form factors were obtained. On the base of these form factors, the elastic scattering amplitude is obtained with taking into account the analytical properties such as unitarity, crossing symmetry, polynomial boundedness. As a result, the united description of the existing experimental data of the differential cross sections and spin correlation parameter \(A_{N}\) ( \(s,t\) ) is obtained with minimum fitting parameters.
