\section{$\eta$ cutting}
\subsection{Cutting $\eta$}
\begin{frame}\frametitle{Cutting $\eta$}

 We have two possibilities to cut $\eta$ away:
 \begin{itemize}
 \item Use MLP:
 	\begin{enumerate}
 	\item In low bins we see bad $M(3\mu)$ distribution. Peaks in in tau mass. 
 	\item We safe signal: we are loosing $32\%$ signal.
  	\end{enumerate}
 \item Veto $\eta$:
 	\begin{enumerate}
 	\item Lover efficiency. $36\%$ lost of signal.
 	\item Safe and easy physics interpenetration.
  	\end{enumerate}
 \end{itemize}

\subsection{Limit Permutations}
\begin{frame}\frametitle{Limit Permutations, Many thanks to Paul}
	\begin{itemize}
	\item OLD: 8.3
	\item NEW, full eta cut: >8.9
	\item New, eta cut high bins: > 8.9
	
	
  	\end{itemize}
  	
Something is wrong.

Limit holds another cross check. We are happy =)
