Current experimental results(SM -observed):

\newline $\Delta sin(2\beta)=2.1\sigma$, tree

\vspace{0.5cm}
Very important probe for new physics! Current experimental average:
$Br(B \rightarrow X_{s} \gamma ) = (3.52\pm0.23\pm0.09) 10^{-4} $

%Theoretical calculation on NNLO:
Theoretical prediction from NNLO:


$Br(B \rightarrow X_{s} \gamma ) = (3.15 \pm 0.23) 10^{-4}$

There are two ways to study this decay:
\begin{enumerate}
\item Exclusive:
\begin{itemize}

 \item The earliest results were done suing a large number of exclusive decays, which were fully reconstructed
\item Errors arising from unseen modes
\item Obsolete for SuperB

\end{itemize}
\item Inclusive:
\begin{itemize}
\item Use tagging to tag the other B 
\item No requirements on $X_{s}$
\item Disadvantage: Cut on photon energy
\item Effort to keep the cut as small as possible

\end{itemize}
\end{enumerate}
Experimentally challenging to measure inclusive decays.
