Evidence for azimuthal correlations in inelastic interactions of56Fe nuclei in emulsion at 2.5A GeV/c

Abstract

Azimuthal correlations in angles between various types of charged secondary particles from inelastic interactions of relativistic 56Fe nuclei with the nuclei of nuclear emulsions have been investigated. It is observed that all types of charged secondaries produced are emitted asymmetrically in the azimuthal plane. The degree of azimuthal asymmetry increases with the decrease of impact parameter. We have also observed that particles belonging to different kinematical regions of the nucleus-nucleus interaction (intergroup correlation) have a tendency to be emitted to the opposite sides in the azimuthal plane.
