$J/\psi$ and $\psi$' suppression in nucleus-nucleus interactions
We report on the production of high mass muon pairs in $p$ - A, S - U and Pb - Pb collisions, as measured by the NA38 and NA50 experiments at the CERN SPS. The ratio between $\psi'$ and $J/\psi$ cross-sections is found to be constant in $p$ - A interactions but decreases from $p$ - A to S - U a...
