Contribution

It provides new insights into the multiplicity distribution and correlations of projectile protons, demonstrating KNO scaling and the dependence on target mass in high-energy nuclear collisions.

Findings

Proton multiplicity correlates strongly with compound and shower particles.

Normalized proton multiplicity is strongly correlated with compound, shower, and heavy ionizing particles.

Proton multiplicity distribution follows KNO scaling across different targets.

Abstract

The present article significantly investigated projectiles lightest fragments (proton) multiplicity distribution and probability distribution with 84Kr36 emulsion collision at around 1 A GeV. The multiplicity and normalized multiplicity of projectiles lightest fragments (proton) is correlated with the compound particles, shower particles, black particles, grey particles, helium fragments particles and heavily ionizing charged particles. It is found that projectiles lightest fragments (proton) are strongly correlated with compound particles and shower particles rather than other particles and the average multiplicity of projectiles lightest fragments (proton) increases with increasing compound, shower and heavy ionizing particles. Normalized projectiles lightest fragments (proton) are strongly correlated with compound particles, shower particles and heavy ionizing charge particles. The multiplicity distribution of the projectiles lightest fragments (proton) emitted in the 84Kr36 + emulsion interaction at around 1 A GeV with different target has well explained by KNO scaling. The mean multiplicity of projectiles lightest fragments (proton) depends on the mass number of the projectile and does not significantly dependent of the projectile energy. The mean multiplicity projectiles lightest fragment (proton) increases with increasing the target mass number.
