\item In SM allows only the charged interactions to change flavour.

\item Other interactions are flavour conserving.

\item One can escape this constrain and produce $\Pbottom \to \Pstrange$ and $\Pbottom \to \Pdown$ at loop level.
\begin{itemize}
\item This kind of processes are suppressed in SM $\to$~Rare decays.
\item New Physics can enter in the loops.

\begin{itemize}
\item No asymmetry $\rightarrow$ Unpolarised photons.

\item Please look at ours: isospin, $A_{CP}$.
\item More results are on their way.
