Estimates of the weak annihilation contributions to the decays B --> $\varrho$ + $\gamma$ and B --> $\omega$ + $\gamma$
The dominant long-distance contributions to the exclusive radiative decays B \to \rho (\omega) + \gamma involve photon emission from the light quarks at large distances, which cannot be treated perturbatively. We point out that this emission can be described in a theoretically consistent way as the...
