Strangeness 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...
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 at SIS energies
In this contribution we discuss the physics of strange hadrons in low energy (' 1 − 2AGeV) heavy ion collision. In this energy range the relevant strange particle are the kaons and anti-kaons. The most interesting aspect concerning these particles are so called in-medium modifications. We will attempt to review the current status of understanding of these in medium modifications. In addition we...
متن کاملStrangeness production at SPS energies
We present a summary of measurements of strange particles performed by the experiment NA49 in central and minimum bias Pb+Pb collisions in the beam energy range 20A 158A GeV. New results on Ξ production in central Pb+Pb collisions and on Λ, Ξ production in minimum bias collisions are shown. Transverse mass spectra and rapidity distributions of strange particles at different energies are compare...
