We compute the J/psipi --> charmed mesons cross section using QCD sum rules. This cross section is important to distinguish the suppression in the production of J/psi through the dissociation by comoving pious and through the formation of quark-gluon plasma. Our sum rules for the J/psipi --> (D) over barD*, D (D) over bar*, (D) over bar *D* and (D) over barD hadronic matrix elements are constructed by using vacuum-pion correlation functions, and we work up to twist-4. After doing a thermal average we get similar to 0.2-0.4 mb at T = 150 MeV. (C) 2003 Elsevier Science B.V. All rights reserved.
