Solid Tracking

Things to do and learn from tracking

• Need to define input and output data structures for tracking code
  • Output from tracking should be standardized so we can easily compare

• Algorithms to try
  • Xin's progressive tracking
    • 3D (present)
    • 2D (track x,y separately and combine)
  • Tree search
  • Mindy's code
  • Others

• Condiderations
  • With and without magnetic fields
  • With field, is there p dependence
  • GEM clustering dependence
  • Calorimeter and other detector information
  • Potential improvements

• Benchmarks
  • Tracking rate
  • Tracking efficiency (#of real tracks reconstructed/# of real tracks)
  • Effect of noise in fits (hits replaced with noise)
  • Pure noise tracks (ghost tracks)
  • Multi-track reconstruction efficiency
  • Helicity dependence of reconstruction (efficiency *and* quality)
  • Noise correlation between planes effects

• Benchmark conditions to map
  • Background rates 0 - x5
  • Background rate derivatives (for helicity dependence)
  • Uncorrelated - correlated backgrounds
  • Readout strip configuration: x/y vs. r/phi
