Collective flow and QCD phase transition

Flow Phenomena as Possible Signals of the Qcd Phase Transition

In recent years azimuthal anisotropies in the particle und energy distributions were observed in collisions of the heaviest nuclei at the Brookhaven AGS and the CERN SPS. Initially such eeects were established in heavy ion collisions at the Bevalac and later studied in much detail in a similar energy regime at the SIS at GSI. These anisotropies are in recent analyses characterized in terms of F...

Chiral Phase Transition in QCD

We employ non–perturbative flow equations to compute the equation of state for two flavor QCD within an effective quark meson model. This yields the temperature and quark mass dependence of quantities like the chiral condensate or the pion mass. Our treatment covers both the chiral perturbation theory domain of validity and the domain of validity of universality associated with critical phenome...

Two Flavour QCD Phase Transition

Results on the phase transition in QCD with two flavours of light staggered fermions from an ongoing simulation are presented. We find the restoration of the chiral SU(2)× SU(2) symmetry, but not of the axial UA(1) symmetry. 1 Deconfinement and Chiral Symmetry There are two symmetries in QCD, each giving rise to a phase transition. For infinite quark mass, ie., pure SU(3) gauge theory, there is...

Dual condensate and QCD phase transition

The dual condensate is a new QCD phase transition order parameter, which connnects confinement and chiral symmetry breaking as different mass limits. We discuss the relation between the fermion spectrum at general boundary conditions and the dual condensate and show numerical results for the latter from unquenched SU(3) lattice configurations.
