Reconstruction Tasks and Topics for Further Development

Focus Areas
We will try to broadly classify outstanding software issues and tasks into three focus areas: Tracking, Calorimetry, and PID. For each of these areas we have appointed a contact person: Simon (Tracking), Matt (Calorimetry), and Paul (PID). The contact person should report progress on the resolution of high-priority issues at each software meeting. A prioritized list of problems and tasks appears below.
Tracking
Issues to Resolve
- wrong track sign choice at pattern recognition stage in FDC
- poor proton reconstruction in b1π events
- incorrect χ2 distributions from track fits: huge peak at zero
- validate propagation of errors from hit level through the fitting procedure to the track level
Questions to Answer
- How do we handle large single Coulomb scattering in tracking, e.g. between the CDC and FDC?
- How do we handle decays in tracking? (This might have similar resolution to the question above since the track shape is similar.)
Calorimetry
Issues to Resolve
- allow easy switch between 1-2-3-4 and 3-3-4 BCAL schemes; include calibrations for both
- tune new BCAL reconstruction algorithm, explore impact on shower multiplicity in b1π events
- include timing reconstruction in FCAL
- correct the error matrix calculation for both FCAL and BCAL
Questions to Answer
- When photons get split into multiple clusters, is all of the energy detected?
- What is our efficiency for π0 detection? η→γγ?
PID
Issues to Resolve
- develop convention for defining t0 for each detector
Questions to Answer
- What is the general scheme (or schemes) that we want to support?
- What is the nature of the user interface into particle ID information?
