2 00 8 Analysis of the B → a 1 ( 1260 ) form - factors with light - cone QCD sum rules

چکیده
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 comes from the parameter ω0 (or λB), which determines the shapes of the two-particle and three-particle light-cone distribution amplitudes of the B meson, it is of great importance to refine this parameter. PACS numbers: 12.38.Lg; 13.20.He

We have analyzed the B → π and Bs → K semileptonic form factors and B → V γ(V = K, ρ, ω) processes in the light-cone QCD sum rules. In order to enhance the predictivity and reliability of numerical results the chiral-current correlator is employed and the twist-3 light-cone wavefunction can be effectively eliminated from the sum rules.

متن کاملM ar 2 00 1 Improved approach to the heavy - to - light form factors in the light - cone QCD sum rules ∗
A systematic analysis shows that the main uncertainties in the form factors are due to the twist-3 wave functions of the light mesons in the light-cone QCD sum rules. We propose an improved approach, in which the twist-3 wave functions don’t make any contribution and therefore the possible pollution by them can be avoided, to re-examine B → π semileptonic form factors. Also, a comparison betwee...

In this work, we study the four form-factors f 1 (Q 2), f 2 (Q 2), g 1 (Q 2) and g 2 (Q 2) of the Σ → n in the framework of the light-cone QCD sum rules approach up to twist-6 three valence quark light-cone distribution amplitudes. The f 1 (0) is the basic input parameter in extracting the CKM matrix element |V us | from the hyperon decays. The four form-factors f 1 (Q 2), f 2 (Q 2), g 1 (Q 2) ...
