Abstract

We calculate the D*Dπ and B*Bπ couplings using QCD sum rules on the light cone. In this approach, the large-distance dynamics is incorporated in a set of pion wave functions. We take into account two-particle and three-particle wave functions of twist 2, 3, and 4. The resulting values of the coupling constants are gD*Dπ=12.5±1 and gB*Bπ=29±3. From this we predict the partial width ...
