Abstract

A novel model-independent Lévy imaging method is employed for reconstruction of the elastic pp and pp¯ scattering amplitudes at low and high energies. The four-momentum transfer t-dependent elastic slope B(t), the nuclear phase φ(t) as well as the excitation function of the shadow profile P(b) have been extracted from data at ISR, Tevatron and the LHC energies. We found qualitative differences in properties of B(t) and φ(t) between pp and for pp¯ collisions that indicate an odderon effect. A proton substructure has also been identified and found to have two different sizes, comparable to that of a dressed quark at the ISR and a dressed diquark at the LHC energies, respectively.
