Statistical coalescence model of J/ψ production at the SPS and RHIC
A recently developed statistical coalescence model of the J/ψ production is presented. The NA50 data on the J/ψ suppression pattern and the transverse mass spectra in Pb+Pb collisions at the SPS are analyzed. The model predictions for the RHIC energies are formulated. The measurements of J/ψ in Au+Au collisions at RHIC are crucial for disentangling the different scenarios of charmonia formation.
متن کاملCharmonium chemistry in A+A collisions at relativistic energies
Charmonium production and suppression in heavy-ion collisions at relativistic energies is investigated within different models, i.e. the comover absorption model, the threshold suppression model, the statistical coalescence model and the HSD transport approach. In HSD the charmonium dissociation cross sections with mesons are described by a simple phase-space parametrization including an effect...
متن کاملAnomalous J/ψ suppression and charmonium dissociation cross sections
We study J/ψ suppression in Pb+Pb collisions at CERN-SPS energies in hadronic matter with energyand temperature-dependent charmonium dissociation cross sections calculated in the quark-interchange model of Barnes and Swanson. We find that the variation of J/ψ survival probability from peripheral to central collisions can be explained as induced by hadronic matter absorption in central collision...
متن کاملJ/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 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...
