The two-meson state consists of the $D^0{\\bar D}^*{}^0$, $D^+D^{*-}$, $J/\\psi\\rho$, and $J/\\psi\\omega$ channels. The energy-dependent decay widths of the $\\rho$ and $\\omega$ mesons are introduced. The $D$-${\\bar D}^*$ interaction is taken to be consistent with a lack of the $B{\\bar B}^*$ bound state. The coupling between the $D{\\bar D}^*$ and $J/\\psi\\rho$ or the $D{\\bar D}^*$ and $J/\\psi\\omega$ channels is obtained from a quark model.
