Quark-meson coupling model and heavy-ion collision

TL;DR

This paper integrates the quark-meson coupling model into a transport simulation to compare nuclear matter properties during Au+Au collisions with those predicted by quantum hadrodynamics.

Contribution

It introduces the quark-meson coupling model into a transport framework and compares its predictions with conventional models for heavy-ion collisions.

Findings

Differences in maximum density reached during collisions.

Interpretation of density differences based on nuclear matter properties.

Comparison highlights model-dependent predictions of nuclear matter behavior.

Abstract

We implement the quark-meson coupling model in Daejeon Boltzmann-Uehling-Uhlenbeck (DJBUU) transport model and perform Au+Au collision simulations at intermediate energies. Results are compared with simulations using a conventional quantum hadrodynamics model. Differences in the maximum density reached during the collisions are interpreted in terms of nuclear matter properties predicted by each model.
