fBs from QCD sum rules
The decay constants of the pseudoscalar mesons B and Bs are evaluated from QCD sum rules for the pseudoscalar two-point function. Recently calculated perturbative three-loop QCD corrections are incorporated into the sum rule. An analysis in terms of the bottom quark pole mass turns out to be unreliable due to large higher order radiative corrections. On the contrary, in the MS scheme the higher...
متن کاملQCD Sum Rules for Skeptics
A new Monte-Carlo based uncertainty analysis is introduced to quantitatively determine the predictive ability of QCD sum rules. A comprehensive analysis of ground state ρ-meson and nucleon spectral properties is performed. Many of the findings contradict the conventional wisdom of both practitioners and skeptics alike. Associations between the phenomenological fit parameters are particularly in...
متن کاملK with QCD sum rules
In this article, we assign the D∗ s3(2860) to be a D-wave cs̄ meson, study the vertices D∗ s3(2860)DK and D ∗ s3(2860)D ∗K in details to select the pertinent tensor structures, calculate the hadronic coupling constants GD∗ s3(2860)DK and GD∗ s3(2860)DK with the three-point QCD sum rules and obtain the decay widths Γ (D∗ s3(2860) → D ∗K) and Γ (D∗ s3(2860) → DK). The predicted ratio R = Γ (D∗ s3(...

In this article, we calculate the masses and residues of the heavy baryons Ω∗c(css) and Ω ∗ b(bss) with spin-parity 3 2 + with the QCD sum rules. The numerical values are compatible with experimental data and other theoretical estimations. PACS number: 14.20.Lq, 14.20.Mr
متن کاملVertex in QCD Sum Rules
The J/ψDD form factor is evaluated in a QCD sum rule calculation for both D and J/ψ off-shell mesons. We study the double Borel sum rule for the three point function of two pseudoscalar and one vector meson current. We find that the momentum dependence of the form factors is different if the D or the J/ψ meson is off-shell, but they lead to the same coupling constant in the J/ψDD vertex. The co...
