The SPS Heavy Ion Programme
During the past fifty years, our concept of an elementary particle has undergone a fundamental change. Today we understand hadrons as bound states of quarks, and thus as composite. In strong interaction physics, quarks have become the smallest building blocks of nature. But the binding force between quarks confines them to their hadron, which cannot be split into its quark constituents. In term...
متن کاملDileptons as Probes of High-Density Hadronic Matter: Results from the SPS Heavy-Ion Programme
The most recent results on dileptons obtained in the CERN heavy-ion programme are reviewed. The emphasis is on the excess of low-mass lepton pairs observed in the CERES, HELIOS-3 and NA38/50 experiments which seems to point at modifications of the vector meson properties, and in particular the ρ meson, in a high density baryonic medium. Recent results on intermediate mass dileptons are also pre...
متن کاملFrom SPS to RHIC: Maurice and the CERN heavy-ion programme
Maurice Jacob played a key role in bringing together different groups from the experimental and theoretical nuclear and particle physics communities to initiate an ultrarelativistic heavy-ion collision program at the CERN SPS, in order to search for the quark-gluon plasma. I review the history of this program from its beginnings to the time when the Relativistic Heavy Ion Collider (RHIC) at Bro...
متن کاملRelating RHIC and SPS Heavy Ion Data
We have demonstrated recently that RHIC heavy ion data concerning particle production at small and intermediate transverse momenta become very transparent, if one realizes that there are two sources of particles production: the corona – due to the interactions of the peripheral nucleons of either nucleus, and the core – representing the high density central zone. We extend our analysis to SPS h...
متن کاملDilepton signals in heavy ion collisions at the CERN SPS
This paper overviews the main results on dilepton and heavy flavour production in heavy ion collisions, obtained in measurements done at the CERN SPS, over the last few years. The presently available results are very interesting, indicating the production of a new state of matter in central Pb-Pb collisions at SPS energies. However, important questions remain open. New and improved measurements...
