Anomalous $J/\psi$ suppression in 158 GeV/c Pb-Pb collisions at the CERN SPS

Heavy ion production of J/ psi mesons has been studied at CERN for a decade, in search for the Quark-Gluon Plasma predicted by lattice QCD. The suppression observed very early in O-Cu, O-U and S-U reactions has been shown to be eventually explained by nuclear absorption, and follow the same exponent...

description Heavy ion production of J/ psi mesons has been studied at CERN for a decade, in search for the Quark-Gluon Plasma predicted by lattice QCD. The suppression observed very early in O-Cu, O-U and S-U reactions has been shown to be eventually explained by nuclear absorption, and follow the same exponential behavior as the proton- nucleus reactions. The new Pb-Pb data deviate from this behavior very strongly, indicating the onset of a new regime in J/ psi suppression. (9 refs).
