摘要:

We review recent theoretical estimates, relevant to the branching ratio of theb→sexclusive transitionB→K*&ggr;. These include the hadronic couplings of the short‐distance effective Hamiltonian, the long‐distance effects and some backgrounds in the search for this decay in high energy experiments, such as at LEP.
