Analysis of the vertex $D^{\ast }{D}^{\ast }\rho$ with the light-cone QCD sum rules

Zhi-Gang Wang, Zhi-Bin Wang

In this article, we analyze the vertex $D^{\ast }{D}^{\ast }\rho$ with the light-cone QCD sum rules. The strong coupling constant $g_{D^{\ast }{D}^{\ast }\rho }$ is an important parameter in evaluating the charmoniu…
