چکیده

Different conclusions about quark nature of f0(980) based on the analysis of data on the reaction φ(1020) → γf0(980) make it necessary to perform detailed comparison of formulae used by various groups for the calculation of partial widths of radiative decays. We carry out a comparative analysis of methods of calculation of radiative decays like φ → γf0 and φ → γη performed by F.E. Close et al., Phys. Rev. D 65, 092003 (2002), and A.V. Anisovich et al., Eur. Phys. J. A 12, 103 (2001); Yad. Fiz. 65, 523 (2002).

Pure Leptonic Radiative Decays B

Pure leptonic radiative decays of heavy-light mesons are calculated using a very simple non-relativistic model. Dominant contribution originates from photon emission from light initial quark. We find BR(B ± → ℓνγ) ∼ 3.5 × 10 −6 and BR(D s → ℓνγ) ∼ 1.7 × 10 −4. The importance of these reactions to clarify the dynamics of the annihilation graph is emphasized.

Decays of the Bc Meson in a Relativistic Quark–Meson Model

The semileptonic decay form factors of the double heavy Bc meson provide a unique opportunity to study the strong interactions between two heavy quarks. A fully relativistic model, with effective non-local quark-meson interactions, is used to compute semileptonic decay form factors, for both the Bc and a wide range of other heavy-light mesons. Using these form factors predictions for decay rate...

Radiative rare B decays revisited

We reexamine contributions of higher K-resonances to the radiative rare decays b → sγ in the limit where both band s-quark are considered heavy. Using the non-relativistic quark model, and the form factor definitions consistent with the HQET covariant trace formalism, we find significant disagreement with previous work which also used heavy quark symmetry, and excellent agreement with experimen...

Radiative leptonic decays of heavy mesons in heavy quark limit

We study the radiative leptonic decays of heavy mesons within the covariant light-front model. Using this model, both the form factors FV and FA have the same form when the heavy quark limit is taken. In addition, the relation between the form factor FV and the decay constant of heavy meson FH is obtained. The hadronic parameter β can be determine by the parameters appearing in the wave functio...

Leptonic Decays of Mesons in a Poincare- Covariant of a Quark Model

Using a relativistic constituent quark model based on point form of relativistic quantum mechanics with given set of degrees of freedom we investigate electroweak decays of the pion and ρ mesons. All free parameters of quark model (the mass u(d) -quark and parameters which determines the confinement scale) are fixed by using relevant experimental data. Leptonic Decays of Mesons in a PoincareCov...
