- Silicon Mis-measured track rate vs pt
- Mis-measured track rate for silicon from JPsi data through Feb 13th 2004
- Sideband subtraction is applied
- Denominator: COT track with silicon r-phi hits found in three layers of SVXII
- Numerator: Silicon track has a negative signed impact parameter 3 sigma from 0. Less than -150um.
- Impact parameter distribution for tracks with all expected silicon hits found
- L00 Performance plots
- An analysis of the impact parameter resolution with L00 is given in this note(see page 18)
- Impact parameter resolution vs pt in the hybrid region
- Fit to asymptotic resolution, multiple scattering component and beamline component
- Squares and triangles are with and without L00 respectively
- Impact parameter resolution vs pt in the silicon only region
- Forward tracking
- Forward Tracking Efficiency
- From central-plug Z events.
- Denominator: Tight central electron and plug calorimeter energy consistent with Z
- Found track associated with plug calorimeter energy. Any tracking algorithm
