Spectator Effects in the Decay B -> K \gamma \gamma

Abstract

We report the results of the first computation related to the study of the spectator effects in the rare decay mode $B\to K\gamma \gamma$ within the framework of Standard Model. It is found that the account of these effects results in the enhancement factor for the short-distance reducible contribution to the branching ratio.
