[en] The modified version of cascade model of hadron-nucleus and nucleus-nucleus collisions has been adopted for simulation of inclusive pion asymmetry in polarized hadron-nucleus interactions. Pion asymmetry in single spin proton-proton collision is used as input in the model. Cascade-cascade interactions, s-wave resonance production and the concept of formation time of secondaries are included into the description of multiparticle production. copyright 1995 American Institute of Physics

[en] The possibility of describing multiparticle production in single-diffractive and non-single-diffractive interactions for pp and p-barp collisions is treated using the hypothesis of statistical cluster emission. The description is valid under the following basic assumptions: 1)The cluster masses grow with collision energy. 2)The rapidity space occupied by clusters depends on inelasticity and collision energy. 3)The decay of clusters of masses M_cl>>m_π is similar to the hadronization processes in w⁺e^- annihilation. An account of the Monte-Carlo simulation model is given. It is shown that there is the changing of the behaviour of single-diffractive cross section in the energy region √s ≅ 50-200 GeV. 43 refs.; 22 figs

[en] Pseudorapidity density distributions of charged particles in heavy-ion collisions have been studied. The results from EMU01 have been compared to the results from the experiments WA80 and E802. The recently obtained pseudorapidity distributions from Au+Au and Au+Ag interactions have been compared to a linear extrapolation from lighter systems. (orig.)
