Book Description
The properties of the strongly interacting matter produced at RHIC are investigated within a chemical and thermal equilibrium chiral SU(3) [sigma]-[omega] approach. The focus is on the freeze-out conditions, the effective masses for the produced hadrons and the expansion of the system. For the freeze-out conditions the commonly adopted noninteracting gas calculations yield temperatures and chemical potentials close to or above the critical temperature for the chiral phase transition, but without taking into account any interactions. Contrary, the chiral SU(3) model predicts temperature and density dependent effective hadron masses and effective chemical potentials in the medium and a transition to a chirally restored phase at high temperatures or chemical potentials. Three different parametrizations of the model, which show different types of phase transition behavior, are investigated. They show that if a chiral phase transition occurred in those collisions, freezing of the relative hadron abundances in the symmetric phase is excluded by the data. Therefore, either very rapid chemical equilibration must occur in the broken phase, or the measured hadron ratios are the outcome of the dynamical symmetry breaking. Furthermore, the extracted chemical freeze-out parameters differ considerably from those obtained in simple noninteracting gas calculations. In particular, the three models yield up to 35 MeV lower temperatures than the free gas approximation. The in-medium masses turn out differ up to 150 MeV from their vacuum values.

Book Description
New theories are explored and discussed on establishing relations between the fundamental theory of strong interactions, known as QCD, and experiment. Powerful theoretical models, known as effective theories, based on symmetries of QCD, have been developed to address the non-perturbative regime of QCD in an approximate, yet quantitatively controllable way. The present workshop focussed on the most recent developments in this area. New results on meson and baryon physics are discussed as well and new directions towards the possible experimental confirmation of nuclear/quark matter and quark-gluon plasma are indicated.
