Weak Decay Form Factors from QCD Sum Rules on the Light-Cone
Form factors of B to light meson transitions are not only needed for the extraction of |Vub| from B → πeν or B → ρeν and |Vts| and |Vtd | from B → Kγ and B → ργ, respectively (provided there is no new physics in these decays), but they also enter most prominently the calculation of B → charmless nonleptonic decays in BBNS factorisation [ 1]. It is hence of eminent importance to calculate them a...
متن کاملThe Decay B → K ∗ γ from QCD Sum Rules Patricia
Using the QCD sum rules approach and the complete leading–logarithmic short–distance coefficients determining the penguin–amplitude, we obtain B(B → K * γ) = (6.8 ± 2.4) · 10 −5 for top–quark masses in the range (150–200) GeV and |V cb | = 0.035 for τ B = 1.5 ps. The ratio to the inclusive rate is B(B → K * γ)/B(B → X s γ) = (20 ± 6)%. Since some time, the penguin–induced decay b → sγ has recei...
متن کامل0(1430)ll decay within QCD sum rules
Form factors of rare B → K 0 (1430)l+l− decay are calculated within three–point QCD sum rules, with K 0 (1430) being the p–wave scalar meson. The branching ratios are estimated when only short, as well as short and long distance effects, are taken into account. It is obtained that the B → K 0 (1430)l+l− (l = e, μ) decay is measurable at LHC. Measurement of these branching ratios for the semilep...
متن کاملA Note on the External-field Method in Qcd Sum Rules
The external-field method has been used extensively in the QCD sum-rule approach to explore various hadron static properties. In the traditional formalism of this method, the transitions from the ground state hadron to excited states are not exponentially suppressed relative to the ground state term and thus contaminate the ground state hadron property to be extracted. In this paper, we suggest...
متن کاملBaryon QCD sum rules in an external isovector-scalar field and baryon isospin mass splittings.
Within the QCD sum-rule approach in an external field, we calculate the baryon matrix element of isovector-scalar current, HB = 〈B|uu−dd|B〉/2MB, for octet baryons, which appears in the response of the correlator of baryon interpolating fields to a constant isovector-scalar external field. The sum rules are obtained for a general baryon interpolating field with an appropriate form for the phenom...
