Sensitivity of the transverse flow towards symmetry energy

TL;DR

This paper investigates how transverse flow in nuclear collisions is affected by symmetry energy at different densities, revealing its sensitivity at sub-saturation densities but insensitivity at higher densities, thus providing insights into nuclear matter properties.

Contribution

The study demonstrates the sensitivity of transverse flow to symmetry energy and its density dependence in the Fermi energy region, highlighting its potential to probe nuclear matter at specific densities.

Findings

Transverse flow is sensitive to symmetry energy at sub-saturation densities.

Transverse flow shows insensitivity to symmetry energy at densities above twice saturation density.

The mechanism behind this sensitivity and insensitivity is discussed.

Abstract

We study the sensitivity of transverse flow towards symmetry energy in the Fermi energy region as well as at high energies. We find that transverse flow is sensitive to symmetry energy as well as its density dependence in the Fermi energy region. We also show that the transverse flow can address the symmetry energy at densities about twice the saturation density, however it shows the insensitivity towards the symmetry energy at densities $\rho/\rho_{0}$ $>$ 2. The mechanism for the sensitivity of transverse flow towards symmetry energy as well as its density dependence is also discussed.
