Study of multiparticle correlations in 200-400 GeV range

Azimuthal correlations at individual events in pp- and pA-interactions at E0=200 and 400 GeV are analysed on the basis of the photoemulsion technology. Single-jet events in two-dimensional planes: mean quasi-rapidity-standard deviation and medium azimuthal angle-standard deviation are detected. It is shown that average multiplicities of single-jet events is considerably less (approximately two-four times) than the average multiplicity of all interactions and they don't depend on the type of the target nucleus. The investigation of events accompanied by full destruction of hevy ions (Ag, Br) has shown isotropic distribution of azimuthal angles of shower particles. It is a new factor in favour of the fact that multiple production of particles in events, accompanying by their full destruction, is of another character in comparison with the production process in an elementary act and in interactions of light and heavy ions. 15 refs.; 3 tabs.; 3 figs
