Description
In relativistic heavy-ion collisions, pseudorapidity is an important kinematic
characteristic because it directly reveals the angular emission pattern, longitudinal dynamics, and
multiparticle creation mechanisms of secondary particles. Because pseudorapidity simply depends
on the emission angle and roughly resembles rapidity at relativistic energies, it is important in
nuclear emulsion studies when momentum information is not immediately available. Thus,
pseudorapidity distributions' shape, width, and target dependency function as sensitive probes of the
space-time evolution of the participant region created during the collision. The pseudorapidity
distributions of shower particles released in krypton–emulsion interactions with an incidence energy
of 1 A GeV are thoroughly examined in this publication. In order to investigate target-mass effects,
the analysis compares interactions with heavy (AgBr) and light (CNO) target nuclei incorporated in
the emulsion. The observation shows that Gaussian functions properly clarify the pseudorapidity
distributions, suggesting that particle emission is collective in nature. A pronounced enhancement in
particle density is observed for AgBr targets relative to CNO targets, highlighting the significant
influence of target size on particle production.
