[en] Recent achievements in high-energy physics are delivered. Data on interaction cross sections, multiplicity, momentum spectra and nature of secondary particles, problems of hadron structure and its manifestation in physics of soft and hard hadron processes in a wide energy range - from 10 to 10⁶ GeV are discussed. The results are compared with the data on lepton and lepton-hadron collisions. The main processes during different nature particle collisions are considered. Interaction mechanisms are analyzed on the basis of quark-parton models and quatum chromodynamic approach

[en] Experimental data on the interactions of light nuclei (d, He(4), C(12)) at the momentum 4.2 GeV/cA with the carbon nuclei were taken in the 2-m propane bubble chamber. The distributions in the number of interacting nucleons, the spectra of protons, the mean energies of secondary pions and protons, the mean fractions of energy transferred to the pion and nucleon components are presented. The results of the investigation of the mechanism of nucleus-nucleus interactions can be used to calculate the nuclear cascades in the atmosphere

[en] Some problems connected with the possibility of constructing a submarine optic Cherenkov detector with the volume of 10⁶ m³ to register neutrino generated during proton solar flashes and neutrino from the accelerator, are considered

[en] The motion of constituent quarks in stationary hadrons is studied experimentally in the framework of the additive quark model. The momentum spectrum of the quarks turns out to be exponential with an average momentum p_q = (1.02 +- 0.02)m_qc in a nucleon and p_q = (1.23 +- 0.03)m_qc in a pion (m_q is the mass of the constituent u and d quarks, m_qc₂ = 0.31 GeV)

[en] An experiment was made with the two-meter propane bubble chamber of the JINR (Dubna). The working volume of the chamber contained a target of three tantalum plates, each I mm thick. The data reported here come from the exposure of the chamber to the beams of p, d, He and C at 4.2 GeV/c

[en] The apperance of asymmetrical production of particles in π-p-interactions at 40 GeV/c has been analyzed by a kinematic method. It is found that the asymmetrical production is connected with a formation of clusters resulting from different Regge pole exchanges. The cross-sections of these processes are measured on the basis of the triple Regge limit. It is shown that analogous events were observed in cosmic ray experiments. (orig.)

[en] The behavior of high-energy particles within nucleus was studied using a classical drop-model approximation. From angular and momentum spectra of secondaries, measured on various nuclei at different energies in accelerator and cosmic ray experiments, the elementary cross-sections for leading hadron interactions in nuclear matter are estimated. It is revealed that energetic secondaries interact less effectively than primaries of the same type. (orig.)

[en] Presented is a modified hydrodynamic model for the cross section set description of PI^-, rho⁰, ω, f, eta particle direct production, secondary particle composition and their distributions on the square of transverse momentum. The suggested model presupposes, that production of every particle type takes place at the temperature T approximately M, but the produced particles continue to cool down, participatin.o in adiabatic expansion of the hydrodynamic model. This approach permits to take account of resonance production within the frames of the hydrodynamic theory; it does not contradict experimental data and it approximately describes their set

[en] It is shown that for the π^-p interactions the distribution symmetry in the Lorentz factor νsub(sq) for nsub(ch) >= 4 relative to the quark collision system takes place. This conclusion confirms definitely the fact of this distribution coincidence with the corresponding distribution obtained for the pp interaction. Interactions with multiplicity of the secondary charged particles close to mean multiplicity are quark-quark interactions. The symmetry of νsub(s2q) distributions for large multiplicities nsub(ch) >= 12 relative to the collision system of π^- meson quark with two proton quarks was shown. This can testify to the fact that these events are the interactions of π^- meson quark with two proton quarks. It was simultaneously established that in these processes there is no contribution of the processes resulted from the interaction of two π^- meson quarks with a proton quark
