J/ psi Suppression in Pb-Pb Collisions: A Hint of Quark-Gluon Plasma Production?


The NA50 Collaboration has recently observed a strong suppression of J/Ψ production in Pb–Pb collisions at 158 Gev/n. We show that this recent observation finds a quantitative explanation in a model which relates the suppression mechanism to the local energy density, whose value is higher in Pb–Pb collisions than in any other system studied previously. The… (More)
