Study of Multiparticle Azimuthal Correlations in Central Nucleus-Nucleus Collisions at Energy of 3.7 GeV per Nucleon

Abstract

The multiparticle azimuthal correlations between protons and between pions in central C-Ne, Mg-Mg, C-Cu and O-Pb collisions at energy of 3.7 GeV/nucleon (Streamer Chamber experiment of JINR) have been studied. The dependence of the azimuthal correlations function on the angle between the transverse momentum vectors sums of particles emitted in forward and backward hemispheres have been studied; A detailed study of pion production in central Mg-Mg collisions have been performed by use of the Lorentz invariant variables; Comparison of the obtained experimental results with predictions of intranuclear cascade model (CASIMIR) and Quark Gluon String Model (QGSM) have been carried out.
