Nonsaturation of theJ/ψSuppression at Large Transverse Energy in the Comovers Approach

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.
