Résumé

The formation of weakly bound clusters in the hot and dense environment at midrapidity is one of the surprising phenomena observed experimentally in heavy-ion collisions from a low center of mass energy of a few GeV up to an ultrarelativistic energy of several TeV. Three approaches have been advanced to describe the cluster formation: coalescence at kinetic freeze-out, cluster formation during the entire heavy-ion collision by potential interaction between nucleons, and deuteron production by hadronic kinetic reactions. Based on the parton-hadron-quantum molecular dynamics microscopic transport approach, which incorporates all three mechanisms for deuteron production, we identify experimental observables, which can discriminate these production mechanisms for deuterons.
