Abstract
This study explores the dynamical formation of deuterons in heavy ion collisions using the Parton-Hadron-Quantum-Molecular Dynamics (PHQMD) approach. Two production mechanisms are investigated: “kinetic” production via “catalytic” reactions and “potential” interactions from nucleon attractive forces. Our analysis thoroughly examines all isospin channels for various reactions and considers deuteron finite-size properties. Results show that accounting for deuteron quantum properties significantly reduces the kinetic contribution in dense medium typical of heavy-ion collisions. Furthermore, by identifying potential deuterons with an advanced Minimum Spanning Tree (aMST) method, we obtain a satisfactory agreement with available experimental data.
