Feasibility of extractingVtd from radiative B(Bs) decays

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

We use experimental information on D-→K*0ϱ- 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, especially B-→ϱ-+γ, are potentially very serious. Estimates based on the annihilation graph are shown to lead to similar conclusions. We emphasize that long-distance (LD) contributions can be appreciably different in B-→ϱ-+γ and B0→ϱ0(ω)+γ. All radiative decays of B, Bs are shown to be governed essentially by two LD and two short-distance (SD) hadronic entities. Despite the presence of considerable LD contributions, we show how separate measurements of B-→ϱ-+γ, B0→ϱ0(ω)+γ, along with the B→K*+γ can be used for a systematic extraction ofV td. Measurements of Bs→ϕ+γ and K*0+γ could also provide very useful consistency checks.

  26. Although the LD contributions from ū u states are expected to be different for B−→K*−+γ with that in B0→K*0+γ (see eqs. (20) and (21)) they are both much too small compared to LD effects from\(\bar cc\) states. Therefore in table I the difference between eqs. (20) and (21) is being disregarded.
