J/ψ Suppression at Sps and Rhic Energies
The NA50 collaboration data 1 on PbPb central collisions at SPS energies has shown a strong suppression of ratio R(ET ) of J/ψ over Drell-Yan (DY) that increases with increasing ET . This suppression has been proposed as an evidence of the obtention of the quark gluon plasma (QGP). We present our results in the framework of an hadronic model 2 (without QGP) and those of a string model which inc...
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...

متن کاملJ / Ψ suppression in nuclear collisions at SPS energies ∗
We have carried out a first calculation of J/Ψ production from nuclear collisions within the covariant transport approach HSD, which has been very successful in describing both hadronic and electromagnetic observables from heavy-ion collisions at intermediate and high energies. The production of J/Ψ’s is based on the Lund string fragmentation model, while its interactions with hadrons are inclu...
متن کاملStrangeness production at SPS energies from NA49
We present results on strange particle production from 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 compared. The energy depend...
