We examine the evolution of a heavy ion collision starting from non-equilibrium to an equilibrium state by looking at the corresponding thermalization times. Therefore we use the hadronic transport model "UrQMD" as microscopic model for high-energetic heavy ion collisions. Unfortunately these times are too long at present because detailed balance is not realized for all collisions which may...

In hydrodynamical modeling of the ultrarelativistic heavy-ion collisions the freeze-out is typically performed at a constant temperature. In this work we introduce a dynamical freeze-out criterion, which compares the hydrodynamical expansion rate with the pion scattering rate [1]. Previous studies [2] have shown that differences between constant temperature and dynamical...

We present results from our recent investigation on the evolution of hadron abundances in heavy ion collisions. We study the production yields of hadrons with strangeness or charm quarks at the chemical freeze-out and their evolutions in the hadronic matter. The scattering cross sections with pions and rho mesons are studied in an effective Lagrangians to describe the dominant hadronic...
