- \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" $\mu$.

- \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.

- \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.
