Relativistic kinetic calculations of heavy ion collisions with phase space dependent fields

Abstract

In transport calculations of heavy ion collisions the effective interactions - mean fields and NN cross sections - have to be determined consistently with the phase space configurations, which is a difficult problem in general. We approximate a solution by constructing self energies for the limiting configurations of colliding and thermalized nuclear matter by extrapolating ground state Dirac-Brueckner results in a consistent way. These self energies are parametrized in the form of effective coupling coefficients. These are then used in relativistic kinetic calculations in a local phase space configuration approximation (LCA). For the transport calculation we use a relativistic extension of the Landau-Vlasov method with Gaussian test particles. We present first results of such calculations which show the sensitivity of various observables to the configuration effects.
