摘要：

The possibility of using a future measurement of the ratio B(B --> rhogamma)/(B --> K*gamma) to improve the constraints on the CKM parameter \V(td)\ is investigated. Special attention is paid to the two main sources of theoretical uncertainties: the SU(3) flavor symmetry-breaking effects and the contribution from final-state interactions.
