Abstract:

We reconsider the `long-range' component of the radiative transition

B \to K~* \gamma

. A careful analysis of the vector dominance amplitude

B \to V_1 V_2 \to V_1 \gamma

is carried out, with emphasis on the role of gauge invariance. The procedure for incorporating phenomenological

B\to V_1 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\to K~*\gamma

radiative transition produced by long-range effects and provide sugggestions for further experimental work.

B: radiative decay
radiative decay: B
K*(892)
effect: long-range
vector dominance
invariance: gauge
B: branching ratio
B: nonleptonic decay
nonleptonic decay: B
helicity: amplitude analysis
