Abstract
The most general form of the Bethe-Salpeter wave functions for the bound states composed of two vector fields of arbitrary spin and definite parity is given. Using the property of vector field ${\ensuremath{\partial}}_{\ensuremath{\mu}}{A}_{\ensuremath{\mu}}(x)=0$, we find that the most general form can be simplified. Then this general form is applied to investigate the bound states composed of two heavy vector mesons and these heavy vector mesons are regarded as resonances. The interaction kernel between two heavy mesons including one light meson $(\ensuremath{\sigma},\ensuremath{\omega},\ensuremath{\rho})$ exchange is considered.
