J/$\psi$ suppression in Pb+Pb collisions at CERN SPS
The NA38 and NA50 experiments at the CERN SPS have measured charmonium production in different colliding systems with the aim of observing a phase transition from ordinary hadronic matter towards a state in which quarks and gluons are deconfined (Quark Gluon Plasma, QGP). In fact it was predicted th...

| description | The NA38 and NA50 experiments at the CERN SPS have measured charmonium production in different colliding systems with the aim of observing a phase transition from ordinary hadronic matter towards a state in which quarks and gluons are deconfined (Quark Gluon Plasma, QGP). In fact it was predicted that the J/$\psi$ yield should be suppressed in deconfined matter. The analysis of the data collected by the NA50 experiment with Pb+Pb collisions at 158 GeV/c per nucleon shows that the J/$\psi$ is anomalously suppressed in central collisions and the observed pattern can be considered as a strong indication for QGP production.
