Abstract

In proton-nucleus and nucleus-nucleus collisions up to central S-U interactions, the P_T-dependence of J/ψ production is determined by initial state parton scattering and pre-resonance nuclear absorption ("normal" J/ψ suppression). The "anomalous" J/ψ suppression in Pb-Pb collisions must reduce the normal P_T broadening, since it occurs mainly in the central part of the interaction region, where also initial state parton scattering and nuclear absorption are strongest. We thus expect for 〈P²_T〉 in Pb-Pb collisions a turn-over and decrease with increasing E_T.
