\begin{enumerate}

\item Truth Matching Ignores Final State Radiation(FSR).
\item Abi example: $\PDzero \to \pi K$ will not give MCtruth because the decay on list is  $\PDzero \to \pi K \gamma$
\item Task: correct this problem, with a on/off switch.

BtaMcAssocGHit
\item They are distributed over packages: BetaCoreTools, BetaMC and BetaMicroTruth.
\item Call mcFromReco is from BtaMcAssocMicro. Than it's checked that particle is a composite and if it is than mcFromRecoComposite is called.

Definition of those functions have to be change in every inheritance class.  
\newline  There is a default argument set to false so old code written by others will not see the difference.

\section{Tests}

\begin{frame}\frametitle{Tests}
I am lazzy =) For The $ \PDzero \to \pi K$ there exists a working code in the tutorial:

\center \href{https://bbr-wiki.slac.stanford.edu/bbr_wiki/index.php/Workbook_Tutorial/A_more_complex_example
}{LINK}
{~}
\end{frame}

\begin{frame}\frametitle{Before the modifications}
\begin{figure}[h] 
\begin{center} 
\mbox{
	{\includegraphics[scale=0.34]{pic/d0_old.png}}
}
\caption{183 events in data sample}
\end{center}
\end{figure}

\end{frame}


\begin{frame}\frametitle{After modifications and FSR==true}
\begin{figure}[h] 
\begin{center} 
\mbox{
	{\includegraphics[scale=0.34]{pic/do_new.png}}
}
\caption{230 events in data sample}
\end{center}
\end{figure}
For now looks ok. 
\end{frame}

\begin{frame}\frametitle{Consistency test old vs new with FSR == false}
\begin{figure}[h] 
\begin{center}

	{\includegraphics[scale=0.2]{pic/d0_old.png}}
		{\includegraphics[scale=0.2]{pic/d0_old.png}}	
}

\end{center}
\end{figure}
Spot  difference =P. They have the same number of events:  183.


\end{frame}

\begin{frame}\frametitle{Consistency test 2}
Do we really get truth D0 in ntuple?

\begin{figure}[h] 
\begin{center} 
\mbox{
	{\includegraphics[scale=0.2]{pic/mc_mass.png}}
}

\end{center}
\end{figure}
I don't know different particle whith mass so close do $\PDzero$ so i think I can declare it that it works. (I also worked in decay tree =) )
