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

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