$J/\psi$ and ${\psi }^{\prime }$ suppression by comovers in Pb+Pb collisions

Abstract

Measurements of $\psi$ and ${\psi }^{\prime }$ production at the CERN SPS are compared to predictions based on a hadronic model of charmonium suppression. Detailed information is presented to facilitate comparison to other analyses. Sensitivity of these conclusions to the model parameters is discussed.
