System evolution of forward-backward multiplicity correlations in a multi-phase transport model

TL;DR

This study investigates how the initial geometric configuration of light nuclei affects forward-backward multiplicity correlations in relativistic collisions, using a multiphase transport model to reveal potential experimental probes for nuclear structure.

Contribution

It demonstrates that the initial geometry influences multiplicity correlations and suggests using these correlations to identify alpha-clustered structures in nuclei.

Findings

$^{16}$O + $^{16}$O collisions produce more isotropic particle distributions.

Forward-backward correlations vary with initial nuclear geometry.

Correlation patterns can help distinguish alpha-clustered nuclei in experiments.

Abstract

The initial geometry effect on forward-backward multiplicity correlations $C(N_{f},N_{b})$ is studied in relativistic collisions between light nuclei by using a multiphase transport model (AMPT). It is found that tetrahedron $^{16}$O + $^{16}$O gives a more uniform and symmetrical fireball which produces a more isotropic distribution of final particles after the expansion and evolution, and leads to a small $C(N_{f},N_{b})$. Forward-backward multiplicity correlation could be taken as a useful probe to distinguish the pattern of $\alpha$-clustered $^{16}$O in experiments by comparing the neighboring colliding nuclear systems like $^{14}$N + $^{14}$N and $^{19}$F + $^{19}$F.
