Uncertainties from long range effects inB→K*γ

We reconsider the ‘‘long-range’’ component of the radiative transition B→${\mathit{K}}^{\mathrm{*}}$γ. A careful analysis of the vector dominance amplitude B→${\mathit{V}}_1$ ${\mathit{V}}_2$→${\mathit{V}}_1$γ is carried out, with emphasis on the role of gauge invariance. The procedure for incorporating phenomenological B→${\mathit{V}}_1$ ${\mathit{V}}_2$ data is identified, and polarization data, only recently available, is employed to estimate the magnitude of the vector dominance effect. We summarize uncertainties in the B→${\mathit{K}}^{\mathrm{*}}$γ radiative transition produced by long-range effects and provide suggestions for further experimental work.
