Heavy Meson Form Factors, Couplings and Exclusive Decays in QCD

Abstract

We discuss the form factors of the heavy-to-light transitions $B\text{ra}\pi$ and $D\text{ra}\pi$, the $B^{\ast }B\pi$ and $D^{\ast }D\pi$ coupling constants, and the nonfactorizable amplitude of the decay $B\text{ra}J/\psi K$ in the framework of QCD sum rules.
