In this article, we analyze the vertex D∗D∗ρ with the light-cone QCD sum rules. The strong coupling constant gD∗D∗ρ is an important parameter in evaluating the charmonium absorption cross sections in searching for the quark-gluon plasmas. Our numerical value for the gD∗D∗ρ is consistent with the prediction of the effective SU(4) symmetry and vector meson dominance theory.
