Abstract
We evaluate the form factor at the H*H pi vertex, for H = B and D mesons, i
n a QCD sum rule calculation. Mie study the momentum dependence of the form
factor and conclude that it is not compatible with a monopole form. We use
two different approaches to extract the H*H pi coupling constant.
