Influence of density dependent symmetry energy on Elliptical flow

TL;DR

This paper investigates how density-dependent symmetry energy influences elliptical flow in heavy-ion collisions, using IQMD simulations to identify transition energies and assess sensitivity across a broad energy range.

Contribution

It provides a systematic analysis of the transition energy related to symmetry energy effects using isospin-dependent quantum molecular dynamics models.

Findings

Elliptical flow becomes zero at a specific transition energy.

The study identifies how symmetry energy affects elliptical flow across 50-1000 MeV/nucleon.

Sensitivity of elliptical flow to symmetry energy varies with energy and density.

Abstract

The effect of density dependent symmetry energy on elliptical flow is studied using isospin-dependent quantum molecular dynamics model(IQMD). We have used the reduced isospin- dependent cross-section with hard(H) equation of state to study the sensitivity of elliptical flow towards symmetry energy in the energy range of 50 - 1000 MeV/nucleon. The elliptical flow becomes zero at a particular energy termed as transition energy. A systematic effort has been made to pin down the transition energy for the density dependent symmetry energy.
