Triton-3He relative and differential flows and the high density behavior of nuclear symmetry energy

TL;DR

This paper investigates how the relative and differential flows of triton-3He pairs in heavy-ion collisions can serve as sensitive probes of the high-density behavior of nuclear symmetry energy, using a transport model simulation.

Contribution

It demonstrates that the t-3He relative flow is a powerful observable for constraining the density dependence of nuclear symmetry energy at high densities.

Findings

Triton-3He flows are sensitive to the symmetry energy at high densities.

The relative flow of t-3He pairs can effectively probe the high-density behavior of nuclear symmetry energy.

Transport model simulations show the potential of these flows as experimental observables.

Abstract

Using a transport model coupled with a phase-space coalescence after-burner we study the triton-3He relative and differential transverse flows in semi-central 132Sn+124Sn reactions at a beam energy of 400 MeV/nucleon. We find that the triton-3He pairs carry interesting information about the density dependence of the nuclear symmetry energy. The t-3He relative flow can be used as a particularly powerful probe of the high-density behavior of the nuclear symmetry energy.
