Study of Multiparticle Azimuthal Correlations in Central CNe, MgMg, CCu and OPb Interactions at Energy of 3.7 GeV per Nucleon

摘要

Azimuthal correlations between protons and between pions have beeninvestigated in central CNe, MgMg, CCu and OPb collisions at energy of 3.7GeV/nucleon. "Back-to-back" (negative) correlations have been observed forprotons in CNe, CCu and for pi^{-}-mesons in CNe and MgMg collisions. Forpi^{-}-mesons "side-by-side" (positive) azimuthal correlations have beenobserved for heavy systems of CCu and OPb. The Quark Gluon String Modelsatisfactorily describes the experimental results both for protons andpi^{-}-mesons.
