Molecular dynamics description of an expanding / plasma with the Nambu--Jona-Lasinio model and applications to heavy ion collisions at RHIC and LHC energies
arXiv:1210.3476 · doi:10.1103/PhysRevC.87.034912
Abstract
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 and of the transverse momentum spectra of pions and kaons and discuss in detail the hadronisation mechanism.
