  227. \section{PID + GeoMVA}
  228. \begin{frame}\frametitle{Reminder}
  229. {~}\\
  230. Last week I shown that we might gain quite a lot by putting PID inside our GEOMVA. Let's see if we are sensitive to poor description of PID in MC(credits to \textbf{Helge Voss}):

  279. \begin{itemize}
  280. \item The biggest worry is if we can calibrate this channel.
  281. \item The following idea allowes to calibrate our channel on $\PDs \to \phi \pi$.
  282. \item It looks that calibration can be even simpler than the one we make.
  283. \item Ok enough of building attention, let's caught to the chase

  298. \item For free we have 2 mu PID.
  299. \item For signal we need 3.
  300. \item Let's take our $\PDs \to \phi \pi$ and bin our muons in 3D bins of $n_{trk}$, $P_{t,\mu}$, and $\eta_{mu}$.
  301. \item For each of the bins we have a PID distribution for muon
  302. \item Then for the $\pi$ in a given bin we choose a PID according to $\mu$ PID in this bin.
  303. \item $\PB \to K^{*} \mu \mu$ uses a similar approach.
