Constraining a simple hadronization model of relativistic heavy-ion collisions using hadronic observables

A complicating factor in using hadrons as early probes for relativistic heavy-ion collisions is that they can undergo strong final-state rescattering with each other. This potentially causes hadronic observables to reflect the condition of the system at a late stage rather than al 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 collisions at CERN energies. A model parameter set is found which qualitatively agrees with measured single and two-particle observables for Pb+Pb collisions.
