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 a ultra-relativistic 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 reactions. We identify experimental observables, which can discriminate these production mechanisms for deuterons.

  1. Effects of light-cluster degrees of freedom on collective flows in heavy-ion collisions at FOPI energies

    nucl-th 2026-08 conditional novelty 6.0

    Explicitly propagating light clusters in a Boltzmann-Uehling-Uhlenbeck transport model substantially modifies predicted proton v1-v4 flows at low FOPI energies (120-400 A MeV) but not above 600 A MeV.

  2. Modifications in clusterization procedures for heavy-ion collisions: minimum spanning tree, simulated annealing, coalescence

    nucl-th 2025-12 conditional novelty 6.0

    The Common Clusterization Library (CCL) provides open-source MST, simulated-annealing, and coalescence cluster finders with a new stable-cluster tracking algorithm, tested against ALADiN and NA49 data.
