The relativistic mean field theory (linear and nonlinear) models are extended to the case of two colliding nuclear matters, relevant to heavy ion scattering and reactions. The effect of vacuum corrections is taken into account through the relativistic Hartree approximation. The Fermi sea is assumed to consist of two colliding Lorentz elongated spheres. A relativistic covariant Pauli correction is considered for the overlap case. This relativistic Pauli correction is found to be very important due to its dependence on the effective nucleon mass which strongly depends on the model equation of state. It is found that by increasing the velocity the energy per baryon increases and saturates at higher densities. The increase in the energy per baryon at low density (the region of no overlap) is much larger than that at high density (the region of large overlap), due to Pauli correction effects. The saturation density of the nonlinear model is shifted to larger values than that of the linear model. Vacuum corrections effects are found to reduce largely te overlap region.

We consider modification of kaons and the implications for dilepton production in the early stage of high-energy heavy-ion collisions. Constructing the equation of state of hadronic matter, including kaons as well as hyperons Λ with recourse to the relativistic mean-field theory, we study the production rate of dileptons. The possibility of K+ condensation is also revisited in this framework.

AbstractWe investigate the relativistic equation of state of hadronic matter and quark-gluon plasma at finite temperature and baryon density in the framework of the non-extensive statistical mechanics, characterized by power-law quantum distributions. We impose the Gibbs conditions on the global conservation of baryon number, electric charge and strangeness number. For the hadronic phase, we study an extended relativistic mean-field theoretical model with the inclusion of strange particles (hyperons and mesons). For the quark sector, we employ an extended MIT-Bag model. In this context we focus on the relevance of non-extensive effects in the presence of strange matter.

Using the collective potential between colliding ions based on the effective nucleon-nucleon interactions of the Skyrme type and the semi-classical Extended Thomas-Fermi approach we describe heavy-ion fusion cross sections applying a Monte-Carlo sampling method of trajectories with the Langevin formalism using friction as described in the so-called Surface-Friction Model.
