1. Status of LHETRACK Tracking with STT+MVD Stefano Spataro
LHETRACK Ferrara Summary
Bug fixes and updates
Performances of STT+MVD tracking
Considerations about the Track Finding

2. LHETRACK Ferrara Summary
Tracking of STT+MVD works!
1 GeV/c -  [20°, 140°]
1 GeV/c -  [20°, 140°]
No improvements from Kalman
(genfit)

3. Bug fixing Several exceptions now are properly handled
Division by zero
Square root of negative volumes
Not initialized hits
SttHelixHit
the code is
much more stable
tested on thousand events
Fixes in Kalman
Wrong initial momentum error
Wrong covariance matrix for MVD (huge)
Rejection of bad tracks
improvements
in genfit results
thanks to Lia and Susanna

4. STT – Momentum Resolution
- [20°, 140°]
GENFIT improves
the resolution

5. STT – Momentum Residual
- [20°, 140°]
Energy loss correction at low momenta

6. STT – Tracking Efficiency
- [20°, 140°]
Efficiency loss

7. STT/TPC – Tracking Efficiency
- [20°, 140°]
the algorithm has lower efficiency only for STT

8. conformal space
STT
TPC -
p = 1 GeV
 = 60°
 = 60°

9. something wrong with STT Helix Hit
conformal space
STT
TPC -
p = 0.2 GeV
 = 60°
 = 60°
something wrong with STT Helix Hit

10. Summary Open Issues LHETRACK code more stable (several fixes)
GENFIT Kalman is working properly
Open Issues
Reco Hits: are they correctly implemented? (cov matrix)
STT Low efficiency: check STT Helix Hit
