\item $\sigma_{c\overline{c}}^{8TeV}=\sigma_{c\overline{c}}^{7TeV}\times \dfrac{8}{7} = 6950 \pm 1100 \mu b$

\begin{frame}\frametitle{Conclusions on TMVA}
{~}\\
\begin{itemize}
\item Each of the signal components is enormously larger than MVA trained on mix.
\item Method looks very promising if we can find a nice blending method(work for next week).
\item Mayby discusion on TMVA/MatrixNet/Neurobayes is next to leading order effect compared to this method?
