[Suppression?].

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 P b−P b 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 P 2 T in P b −P b collisions a turnover and decrease with increasing E T .
