Relative Contributions of Cross-Even and Cross-Odd Parts to the Spin-Dependent Elastic Hadron Scattering Amplitudes at High Energies

The form and energy dependence of different terms of the cross-even and cross-odd parts of the elastic nucleon–nucleon scattering amplitude is determined in the framework of the High Energy Generalize Structure (HEGS) model. In the framework of the HEGS model, using the electromagnetic and gravitomagnetic form factors, the differential cross sections in the Coulomb Nuclear Interference (CNI) region and at large momentum transfer are described well in a wide energy region simultaneously. It is shown that the cross-even part includes the soft pomeron growing like log(s) \({}^{2}\) and an additional term with a large slope and with log(s) growth. The cross-odd part includes the maximal odderon term and an additional oscillation term log(s) growth. It is shown that both additional terms are proportional to charge distributions, but the maximal odderon term is proportional to matter distributions.
