Clusters as a probe of the equation-of-state of strongly interacting matter

Key Points

This research aims to examine the effects of the equation-of-state on light cluster production in heavy-ion collisions.
Utilized the Parton-Hadron-Quantum-Molecular Dynamics (PHQMD) transport approach.
Incorporated a momentum-dependent potential for baryon-baryon interactions derived from the soft equation-of-state.
Analyzed light cluster production in context of the new potential.
Light cluster production is influenced by the momentum-dependent potential compared to previous static models.
The study clarifies the role of dynamic interplay in the creation of strongly interacting matter.

Abstract

We investigate the influence of the equation-of-state (EoS) of strongly interacting matter created in heavy-ion collisions on the light cluster and hypernuclei production within the Parton-Hadron-Quantum-Molecular Dynamics (PHQMD) microscopic transport approach. In earlier PHQMD calculations, nucleon interactions were modeled using a static, density-dependent potential corresponding to the soft and hard equation-of-state. In this study, we incorporate a momentum-dependent potential for the baryon-baryon interaction, derived from the soft EoS. We study the influence of momentum dependent potential on light cluster production.},
