Phase Transitions in QCD
At high temperatures or densities, hadronic matter shows different forms of critical behaviour: colour deconfinement, chiral symmetry restoration, and diquark condensation. I first discuss the conceptual basis of these phenomena and then consider the description of colour deconfinement in terms of symmetry breaking, through colour screening and as percolation transition.
متن کاملHadron Resonaces from QCD
I describe how hadron-hadron scattering amplitudes are related to the eigenstates of QCD in a finite cubic volume. The discrete spectrum of such eigenstates can be determined from correlation functions computed using lattice QCD, and the corresponding scattering amplitudes extracted. I review results from the Hadron Spectrum Collaboration who have used these finite volume methods to study ππ el...
متن کاملHadron formation in relativistic nuclear collisions and the QCD phase diagram.
We study particle production in ultrarelativistic nuclear collisions at CERN SPS and LHC energies and the conditions of chemical freeze-out. We determine the effect of the inelastic reactions between hadrons occurring after hadronization and before chemical freeze-out employing the ultrarelativistic quantum molecular dynamics hybrid model. The differences between the initial and the final hadro...
متن کاملThermal hadron production in relativistic nuclear collisions: the hadron mass spectrum, the horn, and the QCD phase transition
We present, using the statistical model, a new analysis of hadron production in central collisions of heavy nuclei. This study is motivated by the availability of final measurements both for the SPS (beam energies 20-160 AGeV) and for the RHIC energies ( √ sNN=130 and 200 GeV) and by updates in the hadron mass spectrum, which is a crucial input for statistical models. Extending previous studies...
متن کاملHadron production in ultra-relativistic nuclear collisions and the QCD phase boundary
We update briefly our understanding of hadron production in relativistic nucleusnucleus collisions in terms of statistical models with emphasis on the relation of the data to the QCD phase boundary and on a puzzle in the beam energy dependence. 1. Hadron yields, statistical description, and the phase boundary to the QGP. Hadron yields or more specifically yield ratios observed in central nuclea...
