摘要：

We analyse the vertex D*D*rho with the light-cone QCD sum rules. The strong coupling constant g(D*D*rho) is an important parameter in evaluating the charmonium absorption cross sections in searching for the quark-gluon plasmas. Our numerical value for the g(D*D*rho) is consistent with the prediction of the effective SU(4) symmetry and vector meson dominance theory.
