We investigate the density dependence of the symmetry energy in a relativistic description by decomposing the iso-vector mean field into contributions with different Lorentz properties. We find important effects of the iso-vector, scalar δ channel on the density behavior of the symmetry energy. Finite nuclei studies show only moderate effects originating… (More)

We show that in collisions with neutron-rich heavy ions at energies around the production threshold K0 and K+ yields probe the isospin-dependent part of the nuclear equation of state at high baryon densities. In particular, we suggest the K0/K+ ratio as a promising observable. Results obtained in a covariant relativistic transport approach are presented for… (More)

The nuclear symmetry energy as a function of density is rather poorly constrained theoretically and experimentally both below saturation density, but particularly at high density, where very few relaevant experimental data exist. We discuss observables which could yield information on this question, in particular, proton-neutron flow differences, and the… (More)

We show that the phenomenology of isospin effects on heavy ion reactions at intermediate energies (few AGeV range) is extremely rich and can allow a " direct " study of the covariant structure of the isovector interaction in the hadron medium. We work within a relativistic transport frame, beyond a cascade picture, consistently derived from effective… (More)

The production/absorption rate of particles in compressed and heated asymmetric matter is studied using a Relativistic Mean Field (RM F) transport model with an isospin dependent collision term. Just from energy conservation in the elementary produc-tion/absorption processes we expect to see a strong dependence of the yields on the basic Lorentz structure… (More)
