Azimuthal correlations of secondary particles in collisions between gold nuclei and track-emulsion nuclei at a gold-nucleus energy of 10.6 GeV per nucleon

Charged secondaries from collisions of gold nuclei with track-emulsion nuclei showed azimuthal correlations consisting in (i) the asymmetric emission of projectile and target fragments in opposite directions and (ii) an azimuthal quasicollinearity of shower particles in individual events. The measurement errors were investigated and taken into account. The experimental data in question can be interpreted within the model of Gaussian distributions of transverse momentum components.
