title: Nonsaturation of the J/psi suppression at large transverse energy in the comovers approach
abstract: We show that, contrary to recent claims, the J/psi suppression resulting from its interaction with comovers does not saturate at large transverse energy E(T). On the contrary, it shows a characteristic structure-a change of curvature near the knee of the E(T) distribution-which is due to the E(T) (or multiplicity) fluctuation. This change of curvature is also present in recent experimental results, although the experimetal effect is larger than in our calculation.
