[en] State of experimental and theoretical investigations of spin effects at high energies at storage accelerator complxes (SAC) is briefly reviewed in order to obtain new data on hadron structure and mechanism of particle interaction. Problems of elastic scattering with low transfered momenta are considered taking polarization study in π^-p → π⁰n reaction and the mechanism of total cross-section growth with energy increase as examples. Elastic hadron scattering in the region of large angles where the mechanism of quark and gluon interaction and hadron composite structure are manifested plainly is discussed. Experimental data obtained when studying these interactions testify to pronounced dependence of the dynamics of hadron component interaction on their spin freedom degrees. Various quark models, considering nonzero polarization in processes of large angle scattering are studied briefly. Inelastic binary reactions at fixed transfered momenta which are of great interest for studying interaction of valent quarks are discussed. Concrete proposals for the programs of experimental investigations of spin effectat SAC for all considered interactions are given

[en] Polarization effects at large angle elastic scattering are considered. The polarization parameter and the differential cross-section for the scattering of scalar particle on spin 1/2 particle are calculated in the framework of the generalized reaction matrix method. It is shown that spin-dependent effects play an important role in large angle elastic scattering and give an essential contribution to the differential cross-section

[en] Dynamical properties of a+b → c+d inelastic binary reaction have been considered. Universal regularities which should obey the behaviour of angular distributions and polarization parameter in these reactions at -t ≥ 1 (GeV/c)² have been found. These regularities are a dynamical manifestation of the effects connected with unitarity of the scattering matrix. Comparison with experimental data has been made

[en] We asses a role of the double helicity-flip amplitudes in small-angle elastic pp-scattering and obtain a new unitary bound for the double helicity-flip amplitude F₂ in elastic pp-scattering at small values of t on the basis of the U-matrix method of the s-channel unitarization

[en] Spin effects in π^+-, K^+-p, pp inelastic scattering and in inclusive hyperon production in hadron interactions at high energies are discussed. Theoretical approaches to the description of these effects are also considered

[en] Three-dimensional dynamic equation in QFT for the scattering amplitude is used to analyse large-angle pp-scattering with account for all of its spin components. The expressions for spin-spin correlation parameters Asub(nn)(π/2) and Asub(ll)(π/2) have been obtained. They reveal oscillations with s exchange (where s is total energy square of system). Such a behaviour allows one to understand the experimental data, obtained at ZGS energies. The asymptotic values of the parameters Asub(nn)(π/2) and Asub(ll)(π/2) appear to be 1/3 and -1/3 respectively

[en] The model developed previously to describe spin phenomena reproduces the energy dependence of A_nn parameter observed at the ZGS and AGS energies and fixed p_{perpendicular}

[en] Predictions of various models for the P₀ polarization parameter in the π^-p→π⁰n charge exchange reaction are discussed. Investigation of polarization in the range of large values of transferred momentum is of great interest from this point of view. The large P₀ value observed would show the importance of accountancy of the initarity relation when constructing the amplitudes for processes with quantum number exchange

[en] The asymptotic behaviour of hadron form factors is discussed on the base of the model of elastic scattering and diffraction dissociation processes. The results are compared with experimental data. The relation between the behaviour of form factors at Q² → reversible and the rate of the growth of total cross-sections is derived

[en] A model for description of hadron elastic scattering and diffraction dissociation processes is proposed. The model is based on the solution of QFT single-time dynamic equations for the amplitudes of 2→2 and 2→n transitions and also on the notions on the quark structure of hadrons. The problem of polarization in inclUsive Λ production is considered. In the model the Λ-particle polarization is caUsed by the mechanism of polarization on the s anti s qUark pair
