J/ψSuppression in Pb+Pb Collisions: A New Look at Hadrons vs. Plasma

Abstract

A reexamination of hadronic comover scattering indicates that this mechanism cannot explain the observed $\psi$ suppression in Pb+Pb interactions. The possibility of quark-gluon plasma formation is therefore considered.
