Abstract:
The production of J/ψ and ψ' charmonium states in proton-nucleus interactions has been
investigated by the NA50 experiment, at the CERN SPS. High statistics data sets were collected with
collisions induced by 450 GeV protons incident on Be, Al, Cu, Ag andWtargets. The J/ψ and ψ' production
cross-sections have been determined for each p-A system and their dependences on the nucleus size have
been studied, leading to the so-called normal nuclear absorption. Comparing the two patterns we see that
the nuclear absorption is stronger for the ψ' than for the J/ψ. Given the high statistics of the data samples, the xF (or rapidity) differential cross-sections of the J/ψ and ψ' states have also been studied, for each of
the target nuclei.
