\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}

Work done:
\begin{itemize}
\item Prepare a decfile. v27r8 released
\item Simulated $1.3M$ events, pythia8, siom08.
\item Implemented isolation parameters in DecayTreeTuple package(extrnal c++ module).
\item Started looking at signal efficiency.
\item Signal is split into two samples: Downstream $\mu$ and "normal" $\mu$.

\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.

Where do we stand(last week development):
\begin{small}
\begin{itemize}
\item Over 20 new DecFiles committed(Patrick will kill me).
\item No more problem with reweighing the MC. \Simley{1}
\item Smaller systematics.
\item Implemented Generator cuts. Gained 10x in retention.
\item Produced yesterday ntuples with new MC(done by me).
\item Background grown more than expected in 2012.
\item Investigating new trigger lines.
\item Will have the conclusion on triggers for tomorrow's $\tau \to 3\mu$ meeting.

Where do we stand(last week development):
\begin{small}
\begin{itemize}
\item I froze preselection.Moved only to PIDNN.(backup slides).
\item Produce ntuples 2011+2012 data.
\item We see enhancement in low $q^2$ region.
\item Problems implementing LCMS.
\item Thrust axis doesn't make sense in LHCb.
\item On Wed soft-QCD prof. Bialas has talk about BEC ,discussion planned.

\begin{itemize}
\item $\Lambda_b \to h \mu$. We found bug in official MC. We have new one since last week. Playing around with isolating parameter.
\item $\Lambda_c \to p \mu \mu$ At midnight DIRAC infromed me that official MC production started.

\begin{itemize}
\item Let's Use the looser proposed PIDNN for preselection(backupslides)
\item We might get into troubles with statistics for K/p modes.
\item We should really start to think about dedicated stripping!
\item Is a paper only with pions a possibility till we get new stripping?
