Evidence of nonstatistical patterns in particle production

Abstract

The angular substructures of particles produced in 208Pb at 158 A GeV/c and 197Au at 11.6 A GeV/c induced interactions with Ag(Br) nuclei in emulsion detector have been investigated. Nonstatistical ring-like substructures of produced particles in azimuthal plane of a collision have been found and their parameters have been determined.
