Abstract
We calculated the strong form factor and coupling constant for the J/ÏD*D* vertex in a QCD sum rule calculation. We performed a double Borel sum rule for the three point correlation function of vertex considering both J/Ï and D* mesons off-shell. The form factors obtained are very different, but they give the same coupling constant.
