Preliminary Results and Conservation Laws of Two-Body Correlation Transport Theory for Heavy ion Collision

Based on the two-body correlation dynamics(TBCD) introduced by Wang et al., we have taken the bine dependent single pride states as working basis to derive the tWo-body correlation transport theory (TBCTT) for describing the dynamical process of HIC. ms theory contains all possible two-body correlation, the timedependent mean field and antisymmetric effect to provide a microscopic descriphon for the dynamical transport process in HIC. As a testing step, we take QMD code without collision term to preduce the bine-dependent coherent single particle basis for TBCTT. Comparing and calculating the different interaction such as Skyme, Coulomb and Yukawa are performed, it indicates that Coulomb and Yukawa intenahon have important effects in HIC, and show that all behaviors of quantities studied are similar to dynamical process of heavy ion collision. The conservation laws of dynamical process of heavy ion collision, the momentum and number of particle are very good,except the energy conservation as no coupling in thes work.
