New J/$\psi$ suppression data and the comovers interaction model

Abstract

New data on the $J/\psi$ suppression both in proton-nucleus and in lead-lead interactions have been presented recently by the NA50 collaboration. We show that these data, together with the final ones on sulfur-uranium interactions, can be described in the framework of the comovers interaction model with a unique set of three parameters : the nuclear absorption cross-section, the comovers interaction cross-section and a single (rescaled) absolute normalization. Expectations for $J/\psi$ suppression at RHIC are also discussed.
