  234. So far we are using:
  235. \begin{small}
  236. \begin{itemize}
  237. \item PIDNN form Chris Jones, and starderd DLL
  238. \item Both are highly correlated!
  239. \item Values correspond to StdLooseKaon, StdLooseProton.
  240. \item $TrkChi2 <3$, $IP<0.1mm$, $IPCHi2<0.5$
  241. \item $ghostProb<0.35$
  242. \item $PVseparationchi2=4$
  243. \end{itemize}

  252. \section{Changes}
  253. \begin{frame}
  254. We should make looser geometric cuts:
  255. \frametitle{Changes}
  256. {~}
  257. \begin{itemize}
  258. \item $IP<0.3mm$
  259. \item $ghostNN<0.3$
  260. \item $IPCHi2<3$
  261. \item $P_t>100MeV$
  262. \item $P>200MeV$

  267.  
  268. \section{PID}
  269. \begin{frame}\frametitle{PID $\pi$}
  270. \begin{itemize}
  271. \item No more DLL.
  272. \item Only $PIDNN$ V2.

  274. \end{itemize}

  307. \begin{frame}\frametitle{Proposed changes}
  308.  
  309. \begin{itemize}
  310. \item Let's Use the looser proposed PIDNN for preselection(backupslides)
  311. \item We might get into troubles with statistics for K/p modes.
  312. \item We should really start to think about dedicated stripping!
  313. \item Is a paper only with pions a possibility till we get new stripping?
  314. \item Code will be fixed today if we reach a consensus.
