Spin phenomena in high-energy hadron scattering

A united approach is developed to the investigation of processes of high-energy small-angle scattering of particles with an arbitrary spin. In the case of weak energy dependence of spin effects it is shown that at superhigh energies there appears a principal new possibility of the existence of the mechanism of ''spin dynamics'' of strong interaction. Manifestation of ''the spin mechanism'' is investigated in a concrete model framework which takes account of the structure of hadrons at large distances. The predictions of these and some other models are considered for the proton-proton and proton-antiproton elastic scattering till √s=40 TeV
