Study of the Central Heavy-Ion Collision with Emulsion at 4.5 A GeV/c
ABSTRACT
We have investigated the main experimental characteristics(multiplicity correlation ,angular distributions and the analysis of emission of the shower particles produced at target fragments in central collisions of 28Si+AgBr at 4.5AGeV/c has shown a formation of hadronic and baryonic clusters. Events of central collisions are defined, here, as those having no projectile charged fragments, even a singly charged one, emitted within 30 of the beam direction.
