THE STRONG gB ∗ ∗ Bπ COUPLING CONSTANT IN FULL QCD.

چکیده
To leading order in α s , the leading and non-leading 1/m b corrections to the excited B * * meson coupling g B * * Bπ is calculated in the framework of QCD spectral moment sum rules in the full theory. Our prediction is in good agreement with the light − cone QCD sum rule result.

Bπ 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∗+ → ...
متن کاملStrong coupling of excited heavy mesons.
We compute the strong coupling constant GB∗∗Bπ (GD∗∗Dπ), where B ∗∗ (D∗∗) is the 0+ P−wave bq̄ (cq̄) state, by QCD sum rules and by light-cone sum rules. The two methods give compatible results in the limit mQ → ∞, 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 contribu...
متن کاملCouplings of heavy mesons with soft pions in QCD
< 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:
متن کاملThe effect of Bπ continuum in the QCD sum rules for the (0, 1) heavy meson doublet in HQET
We study the effect of Bπ continuum in the QCD sum rule analysis of the heavy meson doublet (0+, 1+) in the leading order of heavy quark effective theory. New sum rules are derived for the leading order binding energy Λ̄+, 1 2 and pionic coupling constant g′. PACS number: 12.39.Hg, 11.30.Rd, 13.20.He, 12.38.Lg
متن کاملBπ 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...
