Soft Photon Problem in Leptonic B-decays
We point out at the peculiarity of B → μνμ decay, namely the enhancement of the soft photon events which originate from the structure dependent part of the B → μνμγ amplitude. This may be a dominant source of systematic uncertainty and compromise the projected experimental uncertainty on Γ(B → μνμ). We show that the effect of these soft photons can be controlled if the experimental cut on ident...
متن کاملLeptonic and semi - leptonic B decays
We present results for the semi-leptonic and leptonic decays of B mesons. These non-perturbative matrix elements are important for constraining the CKM matrix. Results are presented for the pseudoscalar and vector decay constants, as well as flavour breaking ratios and heavy quark symmetry relations. We consider the chiral and momentum dependence of the semi-leptonic form factors of the decay B...
متن کاملLeptonic B Decays at BaBar
Rare B decays have always been a standard probe for New Physics (NP) searches. The very low Standard Model (SM) rate of these decays often make them unaccessible with the present experimental datasets, unless NP effects enhance the rate up to the current experimental sensitivity. Moreover, as NP effects can modify the decay kinematic, particular attention must be payed in order to perform a mod...
متن کاملPure 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.
متن کاملPhotonic and Leptonic Rare B Decays
Some selected topics involving photonic and leptonic rare B decays are reviewed. The interest in their measurement for the CKM phenomenology is underlined. They are also potentially interesting in searching for physics beyond the standard model. This is illustrated on the examples of the decays B → (K,K)ll and B → (ρ, ω)γ by contrasting their anticipated phenomenological profiles in the standar...
