B Meson Light-cone Distribution Amplitudes and Heavy-quark Symmetry∗
Recently systematic methods based on the QCD factorization have been developed for the exclusive B meson decays into light mesons (for other approaches see). Essential ingredients in this approach are the light-cone distribution amplitudes for the participating mesons, which constitute nonperturbative long-distance contribution to the factorized amplitudes. For the light mesons (π, K, ρ, K, etc...
متن کاملDlν̃ form factors in Light - Cone Sum Rules and the D - meson distribution amplitude
In this paper we calculate the weak form factors of the decays Bc(B) → Dlν̃ by using the chiral current correlator within the framework of the QCD light-cone sum rules (LCSR). The expressions of the form factors only depend on the leading twist distribution amplitude (DA) of the D meson. Three models of the D-meson distribution amplitude are employed and the calculated form factor FBc→D(0) is gi...
متن کامل8 Analysis of the B → a 1 ( 1260 ) form - factors with light - cone QCD sum rules
In this article, we calculate the B → a1(1260) form-factors V1(q 2), V2(q 2), V3(q 2) and A(q2) with the B-meson light-cone QCD sum rules. Those formfactors are basic parameters in studying the exclusive non-leptonic two-body decays B → AP and semi-leptonic decays B → Alνl, B → Al̄l. Our numerical results are consistent with the values from the (light-cone) QCD sum rules. The main uncertainty co...

متن کامل, φ Decay Form Factors from Light - Cone Sum Rules Revisited
We present an improved calculation of B → light vector form factors from light-cone sum rules, including one-loop radiative corrections to twist-2 and twist-3 contributions, and leading order twist-4 corrections. The total theoretical uncertainty of our results at zero momentum transfer is typically 10% and can be improved, at least in part, by reducing the uncertainty of hadronic input paramet...
