L3 Algorithms Group

• "%" gives expected FTE effort in the month of June 2002.
• Entries with "?" are awaiting confirmation/complaints from individual authors.
• YOUR input needed NOW!

In Progress with p11

• about to go online in next trigger list (received approval at 19th June 2002 meeting):
  • add stand-alone track filters for single electron and single muon triggers.
  • change E_T thresholds for calorimeter stand-alone electron filters.
  • run L3 jet and electron filters using track-based primary vertexing in duplicate L3 scripts.
• global tracking: (online) performance studies - Daniel Whiteson (50%)
• local muons: evaluation of online performance - Martijn Mulders (20%), Martin Wegner (70%?), Stefan Soldner-Rembold (20%?), Christophe Clement (20%)
• calorimeter non-linearity and hot cell killing:
  • infrastructure tests - Marumi Kado (10%?)
  • studying knock-on effects on electrons and jets - Volker Buescher (5%?) + OTHERS NEEDED ???
• studying effects of proposed changes to calorimeter readout thresholds - Marumi Kado (10%?)
• l3fanalyze run online as an "examine" - Michiel Sanders (30%), Elliot Cheu (70%)

Plans for p12

• electron Tool:
  • central track match - Ulla Blumenschein (20%) (*)
  • refined treatment of shower shape - Ulla Blumenschein (40%) (expected t02.26)
  • additional electron id using road method - Volker Buescher + Florian Beaudette (*)
• muon Tool:
  • central track match - Martin Wegner (30%?) (*)
• tau Tool: Yann Coadou (50%)
  • update tracking code (change track extrapolation method, allow cut on # tracks) (*)
  • allow more parameters to be tunable by .rcp or trigger list (*)
• cft-only tracking: Ray Bueselinck (50%?), Robert Illingworth (50%?)
  • speed and efficiency improvements (particularly stereo tracking)
  • update certification for online running with latest data and infrastructure
  • quantitative performance comparison with global tracking
• missing E_T Tool (including studying effects of calorimeter non-linearity and hot cell killing) - Lee Sawyer (50%) (*, except that hot cell information not used?)
• improvements to track-based primary vertex in z - Chris Barnes (*)
• b-tag infrastructure:
  • impact parameter - Per Jonsson (50%) (*)
  • run-by-run knowledge of beam spot position from vertex examine - Michiel Sanders, Per Jonsson.
• cps:
  • unpacking/examine: Chunhui Han: 10%
  • mapping: Chunhui Han 10%
  • monitoring: Abid Patwa/Andre Turcot 5-10% each
• central Infrastructure: Jon Hays (50%?)
  • streaming
  • code review: pushed along by Jon Hays
    • error messages - all authors (5-10%?)
    • timing studiies - Martijn Mulders (10%?)

Stuff that will have to wait for p13

• thumbnail - NOBODY!? identified to do this work! This is URGENT!
• central track-calorimeter mip match for muons - Martin Gruenewald ???
• di-muon filters (also for single muon triggers) - NOBODY!???
• tau Tool: Yann Coadou
  • add tau type. E.g.: exclusive single charged pi, pi + pizero(s), 3-prong.
• track-based 3-D primary vertex finding - Chris Barnes, Per Jonsson
  This is needed for beam spot monitoring (vertex examine currently uses only level 0 information!) as well as being an essential pre-requisite for:
• secondary vertexing
