Abstract
The sum rules for exclusive production of heavy meson pairs in e(+)e(- ) annihilation are used to evaluate the Upsilon(4S) --> B (B) over bar and psi(3770) --> D (D) over bar decay widths. Infinitely heavy quark limit is discussed, and the scaling relation for the quarkonium-meson coupling constant is derived. The B (B) over bar pair contribution in to the leptonic constant f(Upsilon(4S)) is estimated.
