Abstract

The description of heavy-ion collisions up to bombarding energies of a few GeV per nucleon is based on a relativistic transport equation for the baryon phase-space distribution as derived from time-dependent Dirac-Brueckner theory within semiclassical limits. It describes the selfconsistent mean-field dynamics with its momentum-dependent forces as well as the residual nucleon-nucleon collisional history. We analyze the sensitivity of flow observables to the scalar and vector part of the nucleon selfenergy and try to extract information on the nuclear equation of state (EOS) in comparison with experimental data. Furthermore, we provide predictions for K+ spectra for 40Ca + 40Ca collisions from 0.6 GeV/u to 1.5 GeV/u which show a sensitivity to the nuclear equation of state. In the last part of this contribution we compare the theoretical predictions for e+e- spectra with the available data for p+Be and Ca+Ca at 1 and 2 GeV/u where we incorporate the incoherent on-shell nucleon-nucleon and pion-nucleon bremsstrahlung processes, the Dalitz decay of the Δ-particle and π+π- annihilation.
