From fusion to total disassembly: global stopping in heavy-ion collisions

TL;DR

This study uses quantum molecular dynamics to analyze light particle emission and stopping in heavy-ion collisions across various energies, masses, and impact parameters, revealing that light particle multiplicity indicates the degree of stopping.

Contribution

It introduces light complex particle multiplicity as a new indicator of global stopping in heavy-ion collisions, analyzed over a wide energy and mass range.

Findings

Light complex particle multiplicity correlates with stopping.

Maximum stopping occurs in heavier masses during central collisions.

Light particles behave similarly to anisotropic ratios as indicators.

Abstract

Using the quantum molecular dynamics model, we aim to investigate the emis- sion of light complex particles, and degree of stopping reached in heavy-ion colli- sions. We took incident energies between 50 and 1000 MeV/nucleon. In addition, central and peripheral collisions and different masses are also considered. We ob- serve that the light complex particles act in almost similar manner as anisotropic ratio. In other words, multiplicity of light complex particles is an indicator of global stopping in heavy-ion collisions. We see that maximum light complex particles and stopping is obtained for heavier masses in central collisions.
