0(1430)ll decay within QCD sum rules
نویسنده
چکیده
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 semileptonic rare B → K 0 (1430)l+l− can give valuable information about the nature of scalar meson K 0 (1430). e-mail: [email protected] permanent address:Institute of Physics,Baku,Azerbaijan e-mail: [email protected]

The Radiative rare decays B → K∗∗γ in the light-cone QCD sum rule approach
We predict contributions of higher K-resonances to the radiative rare decays b → sγ, in the framework of the QCD sum rules on the light cone, which combines the traditional QCD sum rule method with the description of final state mesons in terms of the light-cone wave functions of increasing twist. Our calculations are restricted to the leading twist-two operators for K∗(892) and to the asymptot...
متن کاملScalar Meson Decay Constants and the Nature of the a0(980)
The a0(980), a0(1450) and K ∗ 0(1430) decay constants are determined using a form of QCD sum rules known to produce a very accurate determination of the ρ decay constant. The ratio of a0(980) toK ∗ 0 (1430) decay constants is shown to be ∼ 0.6, ruling out both the “loosely-bound-KK̄-molecule” and Gribov minion scenarios for the a0(980). Solutions for the isovector scalar spectral function obtain...
متن کاملMagnetic dipole moment of the light tensor mesons in light cone QCD sum rules
The magnetic dipole moments of the light tensor mesons f2, a2 and strange K∗0 2 (1430) tensor meson are calculated in the framework of the light cone QCD sum rules. It is observed that the values of the magnetic dipole moment for the charged tensor particles are considerably different from zero. These values are very close to zero for the light neutral f2 and a2 tensor mesons, while it has a sm...
متن کاملTHE EUROPEAN PHYSICAL JOURNAL A Twist-3 light-cone distribution amplitudes of the scalar mesons within the QCD sum rules and their application to the B → S transition form factors
We investigate the twist-3 light-cone distribution amplitudes (LCDAs) of the scalar mesons a0, K∗ 0 and f0 within the QCD sum rules. The QCD sum rules are improved by a consistent treatment of the sizable s-quark mass effects within the framework of the background field approach. Adopting the valence quark component (q̄1q2) as the dominant structure of the scalar mesons, our estimation for their...
متن کاملMass and Decay Constant of I = 1/2 Scalar Meson In QCD Sum Rule
We calculate the mass and decay constant of I = 1 2 scalar mesons composed of quark-antiquark pairs based on QCD sum rule. The quaukantiquark pairs can be sq̄ or qs̄ (q = u, d) in quark model, the quantum numbers of spin and orbital angular momentum are S = 1, L = 1. We obtain the mass of the ground sate in this channel is 1.410± 0.049GeV. This result favors that K 0 (1430) is the lowest scalar s...
