\textbf{Wednesday}  \begin{itemize}  \item I managed to debug the code, writing a simple vertex displayer in the transverse plane. I produced a simple generation of $e^+ e^- \rightarrow Z \rightarrow b \bar b$ at $\sqrt{s} = 91$ GeV to try to look at the IP distribution   \end{itemize}  \textbf{Thursday}  \begin{itemize}  \item Looking at the list of the mc particles, I don't know how to get the mc truth (in particular I cannot find the mc parent reletionship. I asked to Colin to know if it's possible or not). In this sense it doesn't seem to be possible to have a mc matching algorithm, and studying the isolation and so on.  \item Last year we performed the photon recovery to add the photons produced by bremstralung and FSR. I don't know actually if these are implemented (it seems to be possible to implement in the PYTHIA card the FSR option), and if it's worth to study them.  \item I don't understand how often we might have one jet more (produced by a gluon for instance)...in this case could be useful to clusterize the particles in an exclusive way (but we need to know which algorithm fastejet uses when it clusters jet in an exclusive way.  \item Concerning the b-tagging, It could be nice to have, for each track, the simulated parameters so that we can calculate the IP, smear it with a resolution parametrized by some functions, calculate the significance and obtain something like in the aleph paper.  \end{itemize}
