Planning for tracking developments

This page documents the plans for tracking developments, as discussed at tracking workshops. It was last reviewed at the Tracking workshop on 2009-07-10.

To do items

The status of this list is reported every two weeks at the T-Rec meeting. It was last reviewed at T-Rec on 2009-11-02

Velo pattern recognition

  • Submit latest chi2 tuning of new velo fit as presented in the workshop - done by David (PatVelo tag dhcroft_20090710, in Brunel v35r4). However check chi2 values again on larger files, eventually retuning is needed (David)
  • Understand bug (?) in TELL1 emulation/clustering (see Olivier's talk) (David)

TrackChecker (Stephie)

  • Add criteria for reconstructible B daughters (e.g. we are only interested if all B daughter tracks are reconstructible) - done
  • Add TT hit information
  • Add hit efficiencies - done
  • PatChecker - obsolete, remove from CVS (Stephie)

Fit improvements

  • Check/Set status from FitInitialization and pass it to full kalman fitter (Stephie)
  • Limit outlier removal in fit (Wouter) - Needs revisiting measurement class as separate counting for stereo and x Dof not directly feasible right now
  • Check center of momentum pulls, retune dE/dx if needed (Stephie)
  • unifying the options settings for all track types, make the refit possible on the best container (Kostya, Wouter)

Fast Geometry (Wouter)

2D PV Fit (Mariusz)

  • Bias in PV reco due to non ideal Velo Position

Longer term projects / ongoing work:

  • Tuning of ghost probability for HLT (no fit chi2 available) - Johannes A.

  • Work on TT in tracking (Jonny, Michel)
    • common inerface for adding TT hits to long tracks

  • Work on parameter comparison based method to evaluate efficiency and ghost rate (???)
    • Do we want to change only numerator or as well denominator of efficiency

  • Further studies on New PatVelo Tool (Olivier)
