Description

The properties of pions stemming from the hot and dense reaction stage of relativistic heavy ion collisions are investigated with the Quantum Molecular Dynamics model. Pions originating from this reactions stage stem from resonance decay with enhanced mass. They carry high transverse momenta. Our calculation shows direct correlation between high pt pions, early freeze out times and high freeze out densities. (orig.)
