Mean field effects in the quark–gluon plasma Original Research Article

A transport model based on the mean free path approach for an interacting meson system at finite temperatures is discussed. A transition to a quark–gluon plasma is included within the framework of the MIT bag model. The results obtained compare very well with lattice QCD calculations when we include a mean field in the QGP phase due to the Debye color screening. In particular the cross over to the QGP at about 175 MeV temperature is nicely reproduced. We also discuss a possible scenario for hadronization which is especially important for temperatures below the QGP phase transition.
