An intermediate baryon system formation and the angular distributions of the slow particles emitted in hadron-nuclear and nuclear-nuclear interactions at high energies

TL;DR

This study investigates how the angular distributions of slow particles in high-energy nuclear reactions change with projectile mass, revealing that increased secondary interactions obscure signals of intermediate baryon system formation.

Contribution

It highlights the impact of projectile mass on angular distribution structures and emphasizes the need to consider secondary interactions in event simulations for heavy ion collisions.

Findings

Structure in angular distributions diminishes with heavier projectiles.

Secondary interactions increase with projectile mass, affecting observable signals.

Event generation models should account for secondary interactions to detect intermediate baryon systems.

Abstract

We have analyzed the angular distributions of the b- particles emitted in Kr+Em -reaction at 0.95 A GeV and in Au+Em -reaction at 10.7 A GeV and compared these with lighter projectile experiments for which some structure in the angular distribution of slow particles was observed. The same structure for the b-particles almost disappears by increasing the projectile mass. We believe that it is connected with increasing rates of internuclear secondary interactions which could lead mainly to disappearance of the information about intermediate baryon system formation. We suggest that it should be taken into account at event generation for heavy ion interactions to restore the information on the intermediate baryon system formation.
