The D(∗)Dπ and B(∗)Bπ couplings from light-cone sum rules
We revisit the calculation of the strong couplings D(∗)Dπ and B(∗)Bπ from the QCD light-cone sum rules using the pion light-cone distribution amplitudes. The accuracy of the correlation function, calculated from the operator product expansion near the light-cone, is upgraded by taking into account t...
