\only<1>{
Making a cross check I found out that our geometry is surprisingly higher than last year:
\begin{enumerate}
\item MC11: $17.28\%$
\item Sim08a: $19.14\%$
\end{enumerate}
Didn't believe that $2\%$ is due to the higher CM energy. 
}
\only<2>
{
I run Generator Level MC to studied what has changed. Turns out this is pythia fault:
\begin{enumerate}
\item MC11, pythia6: $17.28\%$
\item Sim08a, pythia6: $17.96\%$
\item Sim08a, pythia6: $19.14\%$
\end{enumerate}
To make story more funny this is true for all MC samples. With Jon Harrison we checked yesterday: $B_s\to \mu \mu$, $D_s \to \eta \mu \nu $ etc.
We will let Gloria know about this. Does this change something in $B_s\to \mu \mu$?

\begin{itemize}
\item Ds is very promising!
\item Our variables in BDT clearly not good for B channels.
\item Studies are ongoing. There are thousands of combinations of different MVA i want to try combine.
