  "abstract": "The general form of the Bethe-Salpeter wave functions for the bound states composed of two vector fields of arbitrary spin and definite parity is corrected. Using the revised general formalism, we investigate the observed \\emph{Y}(3940) state which is considered as a molecule state consisting of $D^{*0}\\bar{D}^{*0}$. Though the attractive potential between $D^{*0}$ and $\\bar{D}^{*0}$ including one light meson ($\\sigma$, $\\pi$, $\\omega$, $\\rho$) exchange is considered, we find that in our approach the contribution from one-$\\pi$ exchange is equal to zero and consider SU(3) symmetry breaking. The obtained mass of \\emph{Y}(3940) is consistent with the experimental value.",
