Formation of hypermatter and hypernuclei within transport models in relativistic ion collisions

Understand

Within a combined approach we investigate the main features of the production of hyper-fragments in relativistic heavy-ion collisions.

• The formation of hyperons is modelled within the UrQMD and HSD transport codes.
• To describe the hyperon capture by nucleons and nuclear residues a coalescence of baryons (CB) model was developed.
• We demonstrate that the origin of hypernuclei of various masses can be explained by typical baryon interactions, and that it is similar to processes leading to the production of conventional nuclei.
