Abstract
The charmonium dissociation by mesons in relativistic heavy-ion reactions is analyzed within the Regge approach. It is shown that the inclusion of the initial and final state interactions in the dissociation of J / Ψ to D ¯ ∗ D ∗ close to threshold increases the cross section significantly and can not be neglected in comparison to the total dissociation rate. This is due to resonant D ¯ ∗ − D ∗ interactions in s close to the masses of the Ψ ( 4.04 ) and Ψ ( 4.16 ) mesons. We also investigate thermal effects of the ( c c ¯ ) width for such processes in the medium. All these effects change both the magnitude and the shape of the cross section as a function of s . The results obtained should be applied in the analysis of open and hidden charm production in heavy-ion collisions.
