Search for a signal on intermediate baryon systems formation in hadron-nuclear and nuclear-nuclear interactions at high energies

TL;DR

This study investigates signals of intermediate baryon system formation in high-energy hadron-nuclear and nuclear-nuclear interactions, revealing regime changes, saturation, and structures in angular distributions linked to percolation clusters.

Contribution

It provides new evidence of intermediate baryon systems and their behavior with increasing nuclear mass, highlighting the role of percolation clusters in particle emission patterns.

Findings

Observed regime change and saturation in interaction characteristics.

Detected structures in angular distributions at low energies.

Found that increasing nuclear mass weakens these structures.

Abstract

We have analyzed the behavior of different characteristics of hadron-nuclear and nuclear-nuclear interactions as a function of centrality to get a signal on the formation of intermediate baryon systems. We observed that the data demonstrate the regime change and saturation. The angular distributions of slow particles exhibit some structure in the above mentioned reactions at low energy. We believe that the structure could be connected with the formation and decay of the percolation cluster. With increasing the mass of colliding nuclei, the structure starts to become weak and almost disappears ultimately. This shows that the number of secondary internuclear interactions increases with increasing the mass of the colliding nuclei. The latter could be a reason of the disintegration of any intermediate formations as well as clusters, which decrease their influence on the angular distribution of the emitted particles.
