The main contribution to the radiative B{yields}K*{gamma} mode is from penguin operators which are quantum corrections. Thus, this mode may be useful in the search for physics beyond the standard model. In this paper, we compute the branching ratio, direct CP asymmetry, and isospin breaking effects within the standard model in the framework of perturbative QCD, and discuss how new physics might show up in this decay.
