THE TRANSVERSE-MOMENTUM DEPENDENCE OF ANOMALOUS J PSI SUPPRESSION/

In proton-nucleus and nucleus-nucleus collisions up to central S-U int eractions, the P-<tau-dependence of J/psi production is determined by initial state parton scattering and pre-resonance nuclear absorption ( ''normal'' J/psi suppression). The ''anomalous'' J/psi suppression in Pb-Pb collisions must reduce the normal P-tau broadening, since it occ urs mainly in the central part of the interaction region, where also i nitial state parton scattering and nuclear absorption are strongest. W e thus expect for [P-<tau(2)] in Pb-Pb collisions a turn-over and decr ease with increasing E-tau. (C) 1997 Elsevier Science B.V.
