Abstract

We employ QCD sum rules to calculate the J/ψDD∗J/\psi DD^* form factors and coupling constant by studying the three-point J/ψD∗DJ/\psi D^*D correlation function. We find that the momentum dependence of the form factor depends on the off-shell meson. We get a value for the coupling which is in agreement with estimates based on constituent quark model.
