\section{$\PKstar\mu\mu$ toy MC results.}


\begin{frame}\frametitle{Reminder}
\begin{itemize}
\item Chris Langenburgh prepared a "official TOY MC" <- LOL
\item With unfolding of the angles done by him.
\item on the $1^{st}$ of April I showed the results for full sample(10M) in $1GeV$ $q^2$ bins.
\item Now the rest of this stupidity.
\end{itemize}



	\textref {M.Chrz\k{a}szcz, N.Serra 2014}
\end{frame}





\begin{frame}\frametitle{MM -  Strategy}
\begin{itemize}
\item 10M events(signal+background) were dived in small ntuples to match the number of events in the real data.
\item Each sample is then fitted(to get signal+bck n. of events).
\item Then we calculate background moments from sidenads and signal window.
\item and extract the signal moments by subtracting the background.


\end{itemize}

\begin{frame}\frametitle{MM -  Strategy 2}
\begin{itemize}
\item Now we need to test unfolding.
\item The simplest way is weight events $\frac{1}{\epsilon}$. 
\item Results are again beautiful.


\end{itemize}

\begin{frame}\frametitle{Appologies}
When I am typing this presentation it's already 2am. So will skip the table with all the errors, if you are interested you can see it tmr on $\PKstar \mu \mu$ meeting.

\begin{frame}\frametitle{Fitting - Strategy}
\begin{itemize}
\item For comparison I investigated how the fit behaves in the same toys.
\item Started with the folded PDFs. 
\item PDF is as follows:
\end{itemize}
\begin{equation}
PDF=sig(m) \times sig(\cos \theta_l , \cos \theta_k, \phi) + bck(m) \times bck(\cos \theta_l , \cos \theta_k, \phi)
\end{equation}
\begin{itemize}
\item For angles in background case second order cheb. polynomials were chosen.

\end{itemize}

\end{frame}

\begin{frame}\frametitle{Fitting - Results}
\begin{itemize}
\item Again will skip the table, cuz it's late
\item Pools plots look ok.
\item Have problems with convergence of the fit in some bins(eff drops down even to 70\%).

\end{itemize}
