\section{Introduction}
 \begin{frame}
        \frametitle{What we are trying to explain}
  	     In July we freeze the selection for $\PBzero \to \PKstar \mu \mu$:  \href{https://twiki.cern.ch/twiki/pub/LHCbPhysics/BdToKstarMuMu/LHCb-INT-2013-058_v1r1.pdf}{LHCb-INT-2013-058}
  	     	 \begin{itemize}
				\item New selection is based on simplified BDT:(less variables, larger dataset)
				\item Modified vetoes for exclusive backgrounds
				\item Moved from Stripping 17 RECO12 $\to$ Stripping 20 RECO14.
				\item A question raised by Tom:
				\begin{itemize}
				\item \begin{center}
				''What is the overlap for the new and old selection\\
on the 2011 data sample?''
				\end{center}
				\end{itemize}
				\item By product: check any potential bias of events not common in both RECOs, check how well we can model this things in MC(needed for acceptance corrections),  
			%	\item First attempt: Take old ntuples and match events using a unique numbers: event-number and run-number.

\frametitle{Summary}
\begin{itemize}
\item The overlap in data is about 64\% when we have the BDT applied and the cuts aligned. 
\item The BDTs contain different variables and do not select the same events. The overlap for the old sample increases from 78 to 84\% when turning off the BDT in the new sample. 
\item Without any selection, the MC predicts an overlap of 95\%. 

\end{itemize}

\begin{itemize}
\item We are getting closer. We need to match $88\%$ (MC) with $83\%$ (DATA).
\item To meet at common point we need to recover the old selection and BDT(work in progress).
\item $p_T$ mystery remains to be solved.
\item Applying an aligned selection (with no BDT), this comes down to 81\%. We know that there is not a complete correlation in e.g. IP $\chi^2$ between a track reconstructed in RECO 12 and 14, which explains this difference.
