Abstract
We show that, contrary to recent claims, the J/psi suppression resulting fr om its interaction with comovers does not saturate at large transverse ener gy E-T. On the contrary, it shows a characteristic structure-a change of cu rvature near the knee of the E-T distriblution-which is due to the E-T (or multiplicity) fluctuation. This change of curvature is also present in rece nt experimental results, although the experimental effect is larger than in our calculation.
