Molecular dynamics description of an expanding $q$/$\bar{q}$ plasma with
the Nambu--Jona-Lasinio model and applications to heavy ion collisions at
RHIC and LHC energies

Rudy Marty, Jörg Aichelin
We present a relativistic molecular dynamics approach based on the Nambu--Jona-Lasinio Lagrangian. We derive the relativistic time evolution equations for an expanding plasma, discuss the hadronization cross section and how they act in such a scenario. We present in detail how one can transform the time evolution equation to a simulation program and apply this program to study the expansion of a plasma created in experiments at RHIC and LHC. We present first results on the centrality dependence of $v_2$ and of the transverse momentum spectra of pions and kaons and discuss in detail the hadronisation mechanism.
