Hadron-hadron collisions at high energies are investigated in the Ultra-relativistic-Quantum-Molecular-Dynamics approach (UrQMD). This microscopic transport model is designed to study pp, pA and A+A collisions. It describes the phenomenology of hadronic interactions at low and intermediate energies ($\sqrt s 5$ GeV, the excitation of color strings and their subsequent fragmentation into hadrons dominates the multiple production of particles in the UrQMD model. The model shows a fair overall agreement with a large body of experimental h-h data over a wide range of h-h center-of-mass energies. Hadronic reaction data with higher precision would be useful to support the use of the UrQMD model for relativistic heavy ion collisions.

Quantum transport theory of nuclear matter

Within the relativistic Dirac-Brueckner approach we discuss the properties of highly-energetic nucleons and deltas in dense nuclear matter. The effective NN and N..delta.. interactions are constructed in a fully self-consistent way and reproduce all known properties of nuclear matter. We calculate the nucleon self-energy and the density-dependent effective NN and N..delta.. cross sections in a nuclear medium. Results show a sizable reduction of the ..delta.. (pion) production cross section and important changes in the ..delta.. absorption cross sections.

Pion-production, pion absorption, and nucleon properties in dense nuclear-matter - relativistic dirac-brueckner approach at intermediate and high-energies

Within the framework of the relativistic Dirac-Brueckner approach, the equation of state of nuclear matter is studied on the basis of a one-boson-exchange interaction. The saturation properties of the ground state and its compressional energy are calculated. The model is extended to nonzero temperature by use of finite-temperature Green's functions for the dressed nucleons. Isotherms in a $P\ensuremath{-}\ensuremath{\rho}$ diagram are obtained which show the existence of a liquid-vapor phase equilibrium below a critical temperature of ${T}_{c}\ensuremath{\simeq}12$ MeV.
