چکیده
We calculate the strong coupling constants gP 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 gP P ∗π, we compute the hadronic decay widths for D ∗∗ → D∗ π and B∗∗ → B∗ π. ∗Permanent address: Institute of Physics, Azerbaijanian Academy of Sciences, Baku, Azerbaijan

QCD Interactions of Heavy Mesons with Pions by Light-Cone Sum Rules
Light-cone QCD sum rules are employed to compute the strong coupling constants: gB∗B∗π, gB1B0π and gB1B∗π, where (B,B ∗) and (B0, B1) are negative and positive parity (0−, 1−) and (0+, 1+) q̄Q doublets. The couplings are calculated both for finite values of the heavy quark mass and in the infinite heavy quark mass limit, deriving sum rules for mQ → ∞. PACS:11.55.Hx,13.20.He
متن کاملExcited Heavy Mesons Decay Formfactors in Light Cone Qcd
The formfactors of B1 → π and D1 → π transitions, where B1(D1) is the 1+ P-wave Q̄γνγ5q meson state, are calculated in the framework of the light cone QCD. Furthermore these formfactors are compared with the pole dominance model prediction using the values of the strong coupling constants gB1B∗π and gD1D∗π, and a good agreement between these two different descriptions is observed.

We compute the strong coupling constant G B B (G D D), where B (D) is the 0 + P?wave b q (c q) state, by QCD sum rules and by light-cone sum rules. The two methods give compatible results in the limit m Q ! 1, with a rather large value of the coupling constant. We apply the results to the calculation of the hadronic widths of the positive parity B and D states and to the chiral loop contributio...

متن کاملSystematic Study on QCD Interactions of Heavy Mesons with ρ Meson
The strong interactions of the negative-parity heavy mesons with ρ meson may be described consistently in the context of an effective lagrangian, which is invariant under isospin SU(2) transformation. Four coupling constants gHHρ, fH∗Hρ, gH∗H∗ρ and fH∗H∗ρ enter the effective lagrangian, where H (H ∗) denotes a pseudoscalar bottom or charm meson (the corresponding vector meson). Using QCD light ...
