摘要
A complete calculation of the leading logarithmic QCD corrections to the effective hamiltonian for the b --> s-gamma decay is presented. It is then applied to find the inclusive branching ratio for the weak radiative BBAR-meson decay. The numerical results are found to be less enhanced but not very different (within 10%) from the ones already present in the literature.
