FEASIBILITY OF EXTRACTING Vtd FROM RADIATIVE B(Bs) DECAYS

Feasibility of Extracting W~ from Radiative B(Bs) Decays

We use experimental information on D– d K*”p– and B ~ + + K“, coupled with flavor independence of QCD, and with vector meson dominance to show that long distance contributions to B + p+ T, especially to B– ~ p– + ~, are potentially very serious. Estimates based on the annihilation graph are shown to lead to similar conclusions. different in B~ p+ T and We emph=ize that long-distance (LD) contri...

Extracting vector mesons magnetic dipole moment from radiative decays

The possibility that the magnetic dipole moment (MDM) of light charged vector mesons could be measured from radiative processes involving the production (τ → ρνγ) and decay (ρ → ππγ) of vector mesons is studied in a model independent way, via the soft-photon approximation. The angular and energy distribution of photons emitted at small angles respect to the final charged particle is found be se...

SLAC - PUB - 6635 BNL - 60709 TECHNION - PH - 94 - 11 Feasibility of Extracting V td from Radiative B ( B S ) Decays

We use existing measurements of D − → K * 0 ρ − and B → ψ + K * , coupled with flavor independence of QCD, and with vector meson dominance to show that long distance contributions to B → ρ + γ are potentially very serious. We note that long distance (LD) contributions can be appreciably different in B − → ρ − + γ and B 0 → ρ 0 (ω) + γ. All radiative decays of B, B S are shown to be governed ess...

Extracting and using photon polarization information in radiative B decays

We discuss the uses of conversion electron pairs for extracting photon polarization information in weak radiative B decays. Both cases of leptons produced through a virtual and real photon are considered. Measurements of the angular correlation between the (Kπ) and (e+e−) decay planes in B → K∗(→ Kπ)γ(∗)(→ e+e−) decays can be used to determine the helicity amplitudes in the radiative B → K∗γ de...
