We present an evaluation of the strong couplings JD^(*)D^(*) and JD^(*)D^(*)pi by an effective field theory of quarks and mesons. These couplings are necessary to calculate pi+J/psi --> D^(*)+barD^(*) cross sections, an important background to the J/psi suppression signal in the quark-gluon plasma. We write down the general effective lagrangian and compute the relevant couplings in the soft pion limit and beyond.

    A QCD sum rule analysis produces masses, pole residues and six on-shell strong coupling constants for the ΛcD(*)N*(1535) and ΛbB(*)N*(1535) vertices.
