A quantitative reanalysis of charmonium suppression in nuclear collisions

We present a quantitative description of $J\mathrm{/}\psi$ and ${\psi }^{\mathrm{\prime }}$ suppression in proton-nucleus and nucleus-nucleus collisions at CERN energies. We use a conventional hadronic framework based on nuclear absorption plus final state interaction of the $J\mathrm{/}\psi$ or ${\psi }^{\mathrm{\prime }}$ with co-moving hadrons.
