Abstract
Using a coherence time extracted from high precision proton-nucleus Drell-Yan measurements and a nuclear absorption cross section extracted from pA charmonium production experiments, we study J/ψ production and absorption in nucleus-nucleus collisions. We find that coherence time effects are large enough to affect the measured J/ψ–to–Drell-Yan ratio. The data at measured by NA38 are reproduced quantitatively without the introduction of any new parameters. However, when compared with recent NA50 measurements for at the data is not reproduced in trend or in magnitude.
