And Qcd Sum Rules in Hqet ⋆
I review recent developments in Heavy Quark Effective Theory (HQET) that lead to an almost model–independent determination of the |Vcb| element of the Cabibbo– Kobayashi–Maskawa matrix from exclusive semileptonic B → D(∗) decays. In particular, I compare the theoretical uncertainties in the B → Dl ν̄ and the B → D l ν̄ decay modes. I discuss the applications of QCD sum rules within HQET to semile...
متن کاملChiral Sum Rules and Duality in QCD
The ALEPH data on the vector and axial-vector spectral functions, extracted from tau-lepton decays, is used in order to test local and global duality, as well as a set of four QCD chiral sum rules. These are the Das-Mathur-Okubo sum rule, the first and second Weinberg sum rules, and a relation for the electromagnetic pion mass difference. We find these sum rules to be poorly saturated, even whe...
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...
متن کاملCouplings in QCD Sum Rules
We calculate the coupling constants, gπNS11 and gηNS11 , using QCD sum rules in the presence of an external meson field. A covariant derivative is introduced within the S11 interpolating field so that in the nonrelativistic limit the field dominantly reduces to two quarks in the s-wave state and one quark in the p-wave state. Our result for the couplings obtained by further making use of the so...
متن کاملDecays in QCD Sum Rules
The form factors relevant to Bq → D∗ q(J = 1−)lν (q = s, d, u) decays are calculated in the framework of the three point QCD sum rules approach. The heavy quark effective theory prediction of the form factors as well as 1/mb corrections to those form factors are obtained. A comparison of the results for the ratio of form factors at zero recoil limit and other values of q2 with the predictions o...
