CONSTRAINING A SIMPLE HADRONIZATION MODEL OF RELATIVISTIC HEAVY-ION COLLISIONS USING HADRONIC OBSERVABLES

A complicating factor in using hadrons as early probes for relativisti c heavy-ion collisions is that they can undergo strong final-state res cattering with each other. This potentially causes hadronic observable s to reflect the condition of the system at a late stage rather than a l an early one. The present work uses a rescattering calculation with resonances to unfold these effects and thus uses measured observables to constrain a simple initial-state hadronization model for Pb+Pb coll isions at CERN energies. A model parameter set is found which qualitat ively agrees with measured single and two-particle observables for PbPb collisions.
