Production of hypertritons in heavy ion collisions around the threshold of strangeness production

TL;DR

This paper investigates hypertriton production in heavy ion collisions near the strangeness production threshold using a quantum molecular dynamics model, emphasizing the role of hyperon rescattering in yield determination.

Contribution

It introduces a detailed simulation approach combining isospin quantum molecular dynamics with phase space coalescence to analyze hypertriton formation.

Findings

Hyperon rescattering significantly affects hypertriton yields.

Hypertritons exhibit properties similar to nuclear matter.

Rescattering is essential for hyperon transport to spectator matter.

Abstract

We use the Isospin Quantum Molecular Dynamics approach supplemented with a phase space coalescence to study the properties of the production of hypertritons. We see strong influences of the hyperon rescattering on the yields. The hypertritons show up to be quite aligned to the properties of nuclear matter underlining the necessity of rescattering to transport the hyperons to the spectator matter.
