Contribution

It introduces a detailed analysis of symmetry energy parametrizations and their impact on fragmentation within an isospin-dependent QMD model.

Findings

Fragment production is sensitive to symmetry energy parametrizations.

Momentum-dependent interactions significantly affect fragmentation outcomes.

Density dependence of symmetry energy influences the collective response in nuclear collisions.

Abstract

The fragmentation of projectile and spectator matter is studied at different incident energies using an isospin-dependent QMD model with reduced isospin dependent cross-section. The sensitivity of the production of fragments is analyzed using different parametrizations of density dependence of symmetry energy. We shall also highlight the collective response of the momentum dependent interactions(MDI) and symmetry energy towards the fragmentation of colliding nuclei at intermediate energies.
