\section{Inflaton analysis}
\subsection{Introduction}
\begin{frame}\frametitle{Inflaton analysis}
Motivation:
\begin{small}
\begin{itemize}
\item Probing low energy particle physics.
\end{itemize}
$ \mathcal{L}_{XSM} = \int\sqrt{-g}d^{4}x (\mathcal{L}_{SM} + \mathcal{L}_{X} + \mathcal{L}_{grav})$ \\

\begin{itemize}
\item Coupling to SM via scalar potential.
\item Solves cosmological problems.
\item Long lived particles. Life time $10^{-9}-10^{-10} s$
\item Mass $1-2 GeV$.
\item Reheats the early universe.\footnote{arXiv:0912.0390, arXiv:1303.4395}
\end{itemize}

\frametitle{Work done so far}

\begin{itemize}
\item We simulated Signal events of$B^0 \to K^{*} X(\mu\mu)$. Using different masses and different life time.
\item Arround $1\%$ of events survive the stripping.
 


\end{itemize}

We propose to change:
\only<1>
{
\begin{itemize}
\item $\mu$ : MIPCHI2DV(PRIMARY) $ > 100 \to 90$
\item $\mu$  Add a cut: (ADOCACHI2CUT(25, '')
\item( AMAXDOCA('') $0.1 \to 0.11$
 \end{itemize}
 Downstream:
 \begin{itemize}
\item $\mu$  : MIPCHI2DV(PRIMARY) $ > 150 \to 135$
\item $\mu$  Add a cut: (ADOCACHI2CUT(25, '')
\item AMAXDOCA('') $0.2 \to 0.22$
\end{itemize}
}
\only<2>
{
$K^{*}$
\begin{itemize}
\item "MIPCHI2DV(PRIMARY)> $25 \to 23 $
 \end{itemize}
 $B^{0}$ :
 \begin{itemize}
\item  BPVIPCHI2()< $60 \to 50$.
\end{itemize}

{~}
\begin{itemize}
\item timming: $0.747 \to 0.818$
\item Retention $0.0240 \to 0 .0410$
 
\end{itemize}

No micro dst possible. Very strange topology of the decay plus isolation parameter will be used.

\section{Summary}
\begin{frame}\frametitle{Summary on inflaton}
\begin{itemize}
\item Good reconstruction of life time.  \Simley{1}
\item Excellent mass resolution. \Simley{1} 
\item Data from 2011 and 2012 are being processing with our preselection on DIRAC as we speak. \Simley{1} 
\item Poor efficiency: $\varepsilon_{rex} \times \varepsilon_{stripping} = 1\%$ 
 \Simley{-1}
 \item Need to investigate if this is due to reco or stripping.
\end{itemize}
