The one-to-one connection between the eikonal phase and the ratio of the elastic and total cross section is shown. Based on new experimental data of Collaboration CDF we analyzed intercept and power of the logarithmic growth of the Born and total Pomeron amplitude.
The spin effects in nucleon-nucleon scattering are calculated in the framework of the dynamic model taking into account interactions at large distances and the strong form factors; the model factorization of the $NN$ amplitude into the spin-dependent hadron-pomeron vertex and high-energy spinless pomeron is obtained. Theoretical predictions for polarization and $A_{nn}$ are made for the diffraction range at the RHIC energies.
Theoretical predictions for the behavior of $A_{LL}$ asymmetry determined by the pomeron-hadron vertex are done. Strong dependence of the asymmetry on the mass creating quarks and transfer momenta is shown.
A careful analysis of the new data of the UA4/2 collaboration reveals that these data give an essentially large value of the $ρ= Re T(s,t)/Im(s,t)$ that does not contradict the early UA4 experiment. There is the reason to think also that this experiment reveals for the first time a real possibility of the existence of the spin-flip amplitude at superhigh energies in the range of small transfer momenta.
Theoretical predictions for the behavior of the slope of the nucleon-nucleon scattering and another parameters of the differential cross sections in the framework of the dynamic model are compared with the recent UA4 data at small transfer momenta and at the centre-of-mass energy of 541 GeV. The predictions at superhigh energies are considered.
