Study on 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 points have been investigated in central CNe, MgMg, CCu, and OPb collisions at an energy of 3.7 GeVucleon. Negative (back-to-back) correlations have been observed for protons in CNe, CCu, and for 250L衺- mesons in CNe and MgMg collisions. For π~- mesons, positive (side-by-side) 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 π~- mesons.
