L3 Algorithms Group

In Progress with p11

• L3 geometry manager -> offline-quality geometry for tracking and muons
• central tracking
  • global tracking
  • CFT-only Tracking:
    • update certification for online running with latest data and infrastructure
    • quantitative performance comparison with global tracking
• track-based primary vertex in z
• calorimeter non-linearity and hot cell killing
• l3fanalyze run online as an "examine"

Plans for p12

• Central Infrastructure:
  • L3 configuration file -> runs database (to enable tracking of calibrations, geometry files, etc.)
  • thumbnail
  • code review:
    • error messages
    • timing
  • monitoring
• Electron Tool:
  • central track match
  • refined treatment of shower shape
  • additional electron id using road method
• Muon Tool:
  • central track match
  • di-muon filters (also for single muon triggers)
  • central track-calorimeter mip match?
• Tau Tool:
  • Allow more than one matched track
  • Allow more parameters to be tunable by .rcp or trigger list.
  • Add tau type. E.g.: exclusive single charged pi, pi + pizero(s), 3-prong.
• CFT-only tracking: speed and efficiency improvements. Ray Bueselinck 50?%.
• Missing ET Tool
• Commission Track-Based 3-D Primary Vertex Finding.
  This is beam spot monitoring (vertex examine currently uses only level 0 information!) as well as being a prelude to:
• B-Tag Infrastructure:
  • impact parameter
  • secondary vertexing
• cps and fps?
• "Physics" Tools, e.g.:
  • mass, delta phi, delta eta calculations
  • identification of physics event types, e.g., psi, upsilon, W, Z, stream definitions?
