TL;DR

This paper investigates the high energy hadron spin flip amplitude using the HEGS model, comparing different forms and analyzing experimental data to support an energy-independent component with specific momentum dependence.

Contribution

It introduces a comparison of hadron spin flip amplitude forms within the HEGS model and supports the presence of an energy-independent component based on experimental data.

Findings

Experimental data support an energy-independent spin flip amplitude component.

The impact parameter analysis compares different amplitude forms.

The momentum dependence aligns with previous theoretical proposals.

Abstract

The high energy part of the hadron spin flip amplitude is examined in the framework of the new high energy general structure (HEGS) model of the elastic hadron scattering at high energies. The different forms of the hadron spin flip amplitude are compared in the impact parameters representation. It is shown that the existing experimental data of the proton-proton and proton-antiproton elastic scattering at high energy in the region of the diffraction minimum and at large momentum transfer give support in the presence of the energy-independent part of the hadron spin flip amplitude with the momentum dependence proposed in the works by Galynskii-Kuraev.
