Radiative Dileptonic Decays of B Mesons
نویسندگان
چکیده
We investigate the radiative dileptonic decays Bs(Bd) → γll within the standard model. Using the constituent quark model, the branching ratios turn out to be around 5× 10 for Bs → γμμ and around 6× 10 for Bd → γμμ, with slightly larger values for Bs(Bd) → γee. Differential spectrums over the dilepton invariant mass are given. The possibility of using these processes to determine the decay constants of Bs or Bd is discussed.

Decay Properties of QQ̄ Mesons in Potential Models and Effective Field Theories
The decay rates of QQ̄ mesons (Q ε c,b) are studied in the NRQCD formalism in terms of their short distance and long distance coefficients. The long distance coefficients are obtained through phenomenological potential model description of the mesons. The mass spectrum of the cc̄ and bb̄ mesons are reviewed in non-relativistic phenomenological quark antiquark potential of the type V (r) = −αc r + ...

The decay rates of QQ̄ mesons (Q ε c, b) are studied in the NRQCD formalism in terms of their short distance and long distance coefficients. The long distance coefficients are obtained through phenomenological potential model description of the mesons. The model parameters that reproduces the mass spectrum of the cc̄, bb̄ and cb̄ mesons are employed to study the decay widths of these mesons. We ext...
متن کاملRadiative Penguin Decays at the B Factories
In this article, I review the most recent results in radiative penguin decays from the B factories Belle and BABAR. Most notably, I will talk about the recent new observations in the decays B → (ρ/ω) γ, a new analysis technique in b → sγ, and first measurements of radiative penguin decays in the B s meson system. Finally, I will summarize the current status and future prospects of radiative pen...
متن کاملExperimental Status of b → s ( d ) γ Decays
Radiative penguin decays provide an indirect probe for physics beyond the Standard Model and contribute to the determination of the CKM matrix elements. Copious quantities of B mesons produced at the B–Factories permit precision measurements of radiative penguin decays. We review the experimental status of the radiative penguin processes b → s(d)γ.
متن کاملRadiative decays of the (0, 1) strange-bottom mesons
In this article, we assume that the (0, 1) strange-bottom mesons are the conventional bs̄ mesons, and calculate the electromagnetic coupling constants d, g1, g2 and g3 using the light-cone QCD sum rules. Then we study the radiative decays Bs0 → B sγ, Bs1 → Bsγ, Bs1 → B sγ and Bs1 → Bs0γ, and observe that the widths are rather narrow. We can search for the (0, 1) strange-bottom mesons in the inva...
