[en] Energy dependence of differential cross section of elastic proton-proton scattering is discussed in the framework of the model, based on using s-channel unitary condition. To obtain energy dependence the model parametrization was accomplished with account of crossing symmetry, based on two main principles: invariance under CPT-transformations and analytical properties of scattering amplitude. It is shown that the model enables to describe the dependence on momentum transfer and the energy of differential cross section of elastic proton-proton scattering in a wide range of energies and momentum transfers

[en] It is shown that a structure discovered recently in the proton-antiproton elastic scattering differential cross section at the SPS-collider energy, √s=540 GeV, can be explained in the framework of an approach based upon solving the direct channel unitarity condition

[en] It is shown that the recently discovered structure in the differential cross section for elastic proton-antiproton scattering at the SPS Collider energy (s)/sup 1/2/ = 540 GeV can be explained in the framework of an approach based on solution of the unitarity condition in the direct channel

[en] Structure of elastic scattering amplitude with respect to impact parameter is studied which is due to the break in differential cross-section. Exact as well as approximate expressions for the correction term are obtained. Numerical calculations are performed for pp-interaction at 1500 GeV

[en] The problem of hadron backscattering at high energies is discussed. General expressions for the scattering amplitude and differential cross section are obtained. Theoretical calculations agree with the experimental data
