General Information

In September 2008, Trigger Studies Group and Trigger Board merged together and formed a unified Trigger Group.

The Trigger Studies Group (TSG) was formed in September 2004. This group provides a forum for presentation of your latest trigger studies and a place to influence and contribute to the development of trigger tools for the experiment.

  1. Visit TSG D0Wiki web pages for most details:
  2. How to include trigger information in MC files
  3. How to calculate luminosity for OR'd triggers
  4. caf_trigger package contains p18-br and p21-br, we recommend to use latest p21-br for both p17 and p20 analyses.
  5. trigeff_cafe package updates: use v00-04-01 tag for RunIIa studies, and v00-05-00 tag (or head version) for RunIIb ones.
  6. Useful DZero Note:
    • Rick's techinical overview of v16 muon triggers (not in the form of D0 Note but as important as one)
    • D0 Note 5409 describes procedures used to measure single EM ORing trigger efficiencies for RunIIA
    • D0 Note 5783 describes procedures used to measure single EM ORing trigger efficiencies for RunIIB
    • D0 Note 5329 describes procedures used to measure single MU ORing trigger efficiencies
    • D0 Note 5587 describes procedures used to measure electron muon ORing trigger efficiencies
    • D0 Note 5093 describes procedures used to measure single JET object trigger efficiencies
    • D0 Note 4882 describes procedures used to calculate multi-object trigger efficiencies
