Study of the Flavour Changing Neutral Current Decay mode $B\to K\gamma \gamma$

Abstract

We study the neutral current flavour changing rare decay mode $B\to K\gamma \gamma$ within the framework of Standard Model, including the long distance contributions. It is found that these long distance contributions can larger than the short distance contribution.
