Popis:	Multiparticle azimuthal correlations of π − mesons have been studied in dC, HeC, CC, CNe, MgMg, (d, He)Ta, CCu, CTa, and OPb collisions at momentum of 4.2, 4.5 GeV/c per nucleon within the standard transverse momentum analysis method of P. Danielewicz and G. Odyniec. The data were obtained by SKM-200-GIBS and Propane Bubble Chamber Collaborations of JINR. The axis has been selected in the phase space and with respect to this axis π − meson correlations were observed. The values of the coefficient of the correlations linearly depend on the mass numbers of projectile (A P ) and target (A T ) nuclei. The Quark-Gluon String Model satisfactorily describes the experimental results.
