Scientific paper

We discuss applications of QCD sum rules on the light-cone to the form factors
of the exclusive transitions $B \rightarrow \pi$ and $D\rightarrow \pi$, and to
the $B^*B \pi$ and $D^*D \pi$ coupling constants. In the light of our results
we examine the pole dominance model for these form factors. A first estimate is
given on the nonfactorizable amplitude of the decay $ B \ra J/\psi K$.
