چکیده
We present the results of a quenched lattice QCD study of the coupling g, in the static heavy quark limit. After combining this with our previous results obtained by using propagating heavy quarks with a mass around the physical charm quark, we are able to interpolate to the b-quark sector. Our results are g ∞ = 0.48 ± 0.

Bπ form factors from QCD Sum Rules
The H * Hπ form factor for H = B and D mesons is evaluated in a QCD sum rule calculation. We study the Borel sum rule for the three point function of two pseudoscalar and one vector meson currents up to order four in the operator product expansion. The double Borel transform is performed with respect to the heavy meson momenta. We discuss the momentum dependence of the form factors and two diff...
متن کاملBπ Couplings in Qcd
We calculate the D∗Dπ and B∗Bπ couplings using QCD sum rules on the lightcone. In this approach, the large-distance dynamics is incorporated in a set of pion wave functions. We take into account two-particle and three-particle wave functions of twist 2, 3 and 4. The resulting values of the coupling constants are gD∗Dπ = 12.5 ± 1 and gB∗Bπ = 29± 3. From this we predict the partial width Γ(D∗+ → ...

< π(q) D(q2)|D(q1, ǫ) >= gD∗Dπ(ǫ · q) (1) governs the decay D → Dπ; from the experimental branching ratio BR(D → Dπ) = 68.1 ± 1.0 ± 1.3 % [1] and from the measurement Γ(D) < 131 KeV [2] the upper limit gD∗Dπ ≤ 20.6 can be derived. The analogous coupling constant in theB channel, gB∗Bπ, describes the contribution of the B ∗ pole to the form factor F 1 (q ) of the semileptonic decay B → πlν:

The coupling gB∗Bπ is related to the form factor at zero momentum of the axial current between Band B-states. This form factor is evaluated on the lattice using static heavy quarks and light quark propagators determined by a stochastic inversion of the fermionic bilinear. The gB∗Bπ coupling is related to the coupling g between heavy mesons and low-momentum pions in the effective heavy meson chi...

The coupling gB∗Bπ is related to the form factor at zero momentum of the axial current between B ∗ and B states. Moreover it is related to the effective coupling between heavy mesons and pions that appear the heavy meson chiral Lagrangian. This coupling has been evaluated on the lattice using static heavy quarks and light quark propagators determined by a stochastic inversion of the fermionic b...
