Charmonia and Drell-Yan production in proton-nucleus collisions at the CERN SPS

Charmonium production in p-A collisions is a unique tool for the study of the interaction of bound ccbar in nuclear matter. It can provide details on the basic features of the resonance formation mechanism and, in particular, on its non-perturbative aspects. In this Letter, we present an experimenta...

description Charmonium production in p-A collisions is a unique tool for the study of the interaction of bound ccbar in nuclear matter. It can provide details on the basic features of the resonance formation mechanism and, in particular, on its non-perturbative aspects. In this Letter, we present an experimental study of Charmonia and Drell-Yan production in proton-nucleus collisions at 450GeV/c. The results are analyzed in the framework of the Glauber model and lead to the values of the nuclear absorption cross-section sigma^abs_pA for j/psi and psi'. Then, we compare the J/psi absorption in proton-nucleus and sulphur-uranium interactions, using NA38 data. We obtain that, for the J/psi, omega^abs_pA and omega^abs_SU are compatible, showing that no sizeable additional suppression mechanism in present S-U collisions, and confirming that the anomalous J/psi suppression only sets in for Pb-Pb interactions.
