The strong coupling constants of excited positive parity heavy mesons in light-cone QCD

Abstract We calculate the strong coupling constants g p ∗∗ p ∗ π , where P ∗∗ (D ∗∗ , B ∗∗ ) is the 1 + p-wave state, in the framework of the light-cone QCD sum rules, and using these values of g p ∗∗ p ∗ π , we compute the hadronic decay widths for D ∗∗ → D ∗ π and B ∗∗ → B ∗ π .
