The search for the quark-gluon plasma study of production of charmed bound states in Pb-Pb collisions at 158 GeV/nucleon.

Abstract : The NA50 Collaboration has studied the production of dimuons originating from J/psi, psi' and Drell-Yan virtual photons in Pb-Pb collisions at 158 GeV/nucleon. The J/psi production differs from what is expected when extrapolating from previously studied colliding systems. Going from peripheral to central collisions, the J/psi suppression presents a sudden and clear drop-off which we refer here as an "anomalous suppression".
