\begin{frame}\frametitle{Propagation from $S_x$ to $P_x$}

\begin{itemize}
\item Using MoM we have a direct access to $S_x$.
\item Some theorist (we all know who ;)) like to have instead $P_x$.
\item We need to provide them the $P_x$ or they will do crazy crazy things with the errors.
\item Reminder:
\end{itemize}
\begin{center}
\begin{equation}
P_1=2/(1-F_l),
\end{equation}
\begin{equation}
P_2=\dfrac{2 A_{fb}}{3}/(1-F_l)
\end{equation}
\begin{equation}
P_3=\dfrac{-S_9}{3}/(1-F_l)
\end{equation}
\begin{equation}
P_{4568}=\dfrac{S_{4578}}{3}/\sqrt{F_l(1-F_l)}
\end{equation}
\end{center}

\begin{frame}\frametitle{MC propagation}

Since we have the full information about the $S_x$ with errors(assymetric) and correlations we can make a TOY MC and see how the $P_x$ behaves. To make a toy we need to simulate a correlated multidimensional Gaussian. I didn't know before hand how to do it so here is the recipe if some one will need it for the future:
\begin{itemize}
\item Simulate multidimensional gauss with with 1 and centred at 0.
\item Correlate the dimensions using Cholesky matrix decomposition.
\item Scale the left and the right tail to the right $\sigma_{L,R}$.
\item Now after this scalling you will have a bump at 0 since you have 50:50 events on left and on the right, which is correct only for $\sigma_{L}=\sigma_{R}$. Reject the $\dfrac{\sigma_{SMALLER}}{\sigma_{LARGER}}$ events from smaller $\sigma$.
\item Move the mean of each Gauss to the value of $S_x$ and voila.


\end{itemize}

\begin{frame}\frametitle{MC propagation, X-checks 1/2}
\begin{itemize}
\item Since this procedure is not form books I wated to be extra carefull and performed super tests.
\item Check that the correlation between $S_i$ and $S_j$ is in my toys are the same as the one I put in. with 100.000 events the differences that I observed are $\mathcal{O}(0.001)$ so oki doki.
\item Check that the $\sigma_{L,R}$ are the correctly simulate. Fitted left and right separately and compare the results. Oki doki.

\begin{itemize}
\item The biggest $F_l$ is observed in $1.1-2.5~\GeV^2$.
\item This is clearly unphysical! We need a smarter way to determine the $P_x$ in this bin. 
\item Will try bootstraping.
