DYNAMIC AND THERMAL ASPECTS OF RELATIVISTIC HEAVY-ION COLLISIONS

Within a covariant BUU-approach we simulate heavy-ion collisions at various bombarding energies from 400 MeV/u to 1 GeV/u. We evaluate locally the energy-momentum tensor T-mu-nu (x), and extract pressures, energy-densities and temperatures. The connection of these thermodynamical quantities to experimental observables and their sensitivity to the equation of state is discussed. Furthermore, we investigate the question of local equilibration and evaluate the entropy produced in these reactions.
