We discuss a model-independent framework for the analysis of the radiative B-meson decays B ~ K% and B --\* tW based on the heavy-quark limit of QCD. We present a factorization formula for the treatment of B --\* V~/ matrix elements involving charm (or up-quark) loops, which contribute at leading po
