CP violation in the decay mode $B\to \pi \gamma \gamma$

Abstract

Within the framework of Standard Model, the exclusive decay mode $B\to \pi \gamma \gamma$ is studied. Although the usual short distance contribution is small compared to the similar $B\to K\gamma \gamma$ mode, the process offers the possibility of studying the CP violation, a feature absent in the $B\to K$ counterpart.
