In these remarks I explain the motivation which leads us to consider chemical nonequilibrium processes in flavor equilibration and in statistical hadroniziation of quark–gluon plasma (QGP). Statistical hadronization allowing for chemical non-equilibrium is introduced. The reesults of fits to RHIC-130 results, including multistrange hadrons, are shown to agree only with the model of an exploding...
متن کاملStrangeness Equilibration at Gsi Energies
We develop the notion of " broad-band equilibration " in heavy-ion processes involving dense medium. Given density-dependent K −-masses we show that the equilibration at GSI energies claimed to hold in previous treatments down to ∼ ρ 0 /4, can be replaced by a broad-band equilibration in which the K −-meson and hyperons are produced in an essentially constant ratio independent of density. There...
متن کاملStrangeness Equilibration at GSI Energies
We argue that both K + and K − must get lighter in dense medium at some density ρ > ρ 0 due to the decoupling of the vector mesons. This modifies significantly the strangeness equilibration as well as kaon condensation scenarios hitherto put forward in the literature. We note that the claimed equilibration density at GSI energies, ∼ ρ 0 /4 – which is much too low – results from a baryon chemica...

As shown in some talks [1] of this conference, statistical descriptions work very successfully for multihadron final states in nucleon-nucleon, nucleon-nucleus, and nucleus-nucleus collisions. In this approach the chemical equilibrium particle ratios are functions of temperature T and baryon chemical potential μB only . Recently GSI measured Au-Au and Ni-Ni collisions at 0.8 ∼ 2.0 GeV. Some mea...
