Track by track analysis, compare calibration production SL24b (old alignment), production SL21c, and TFG25a (new alignmnet) for pp5000_2022.
Legend
The plots are designed to answer on the following questions:
- What is difference between efficiencies for "new" and "old" reconstruction for both global and primary tracks versus kinematical variables ?
- What globals and primaries track relative reconstruction efficiency of "new" production with respect to "old" one?
- What is the track parameters and their errors dependence on the track kinematics (φ, η, 1/pT) ?
- What is difference in the primary vertex positions?
- Filled marker for "new" production, opened marker for "old" one.
- Black marker for positive tracks, red markers for negative tracks.
- The efficiency is calculated for the matched tracks i.e. tracks have one to one match or if there is a multiple match than it is taken the first matched pair only.
- The clones are tracks with more than 1 matched track.
- The lost track are ones without match.
The conclusions:
- There is mismatch between the best primary vertices in old and new production (Fig. 33. Thus, there is NO valid primary track comparsion (Fig. 11-18, and 25-30).
- Global track shows :
slightly higher new efficiencies (Fig. 1-3)
- difference in pT ~ 1%/GeV (Fig. 23)
