Charmonia suppression in nucleus-nucleus interactions at CERN SPS

The NA50 experiment at CERN SPS has studied charmonium production in Pb-Pb collisions at 158 GeV/c per nucleon. According to the theoretical predictions the observation of the suppression of the $J/\psi$ production yield is expected to be an unambiguous probe for a phase transition from ordinary nuc...

Sumario:The NA50 experiment at CERN SPS has studied charmonium production in Pb-Pb collisions at 158 GeV/c per nucleon. According to the theoretical predictions the observation of the suppression of the $J/\psi$ production yield is expected to be an unambiguous probe for a phase transition from ordinary nuclear matter towards a state in which quarks and gluons are deconfined.
