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 <sup>28</sup>Si+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 3<sup>0</sup> of the beam direction

Shower and Slow Particle Productions in Nucleus-Nucleus Collisions at High Energy

“…Study of the secondary charged particles produced in heavy ion collisions is attracting a great deal of attention during the recent ten years. Since the first run of the Dubna Synchrophasotron, in 1980, a lot of data for nuclear fragmentation in light-and heavy-ion collisions at high energy have been collected [1][2][3][4][5]. The measurements show that the average multiplicity of shower, grey particles increases with increase in projectile mass, but the average multiplicity of black particles is approximately constant.…”
