Trigger Content and Function in Release 14

The purpose of this page is to outline the goals for content and function of the offline trigger data at each level of the EDM (RDO/ESD/AOD/DPD/TAG) in Release 14. Size depends on menu and event type, so numbers given are estimates based on rel 13 default menu on ttbar events.

Trigger functions can be broken down into:

  • full detailed analysis of trigger objects and all their properties
  • re-running hypothesis algorithm to study optimizing algorithms and systematic uncertainty on efficiency
  • did a trigger fire or not




Function: study all trigger objects in full detail, re-run hypo, retrieve trigger decision
Content: of ESD is expected to remain basically the same as in release 13.
Size: 200kB


Function: re-run hypo, retrieve trigger decision
Content: should AOD objects be 'thinned' to the minimum required to re-run hypothesis algorithms?
Size: 50kB


Function: retrieve trigger decision
Content: only what is necessary to retrieve the trigger decision (name or just chain ID?)
Size: 2kB



Minimum EDM to Re-Run Hypo

Question: "What is the minimum possible trigger EDM size that can re-run hypothesis algorithms?".
To answer the question, I'm asking each slice coordinator for a list which contains the minimum number of variables (float, int, etc.) required to run their hypo algorithms.

Slice Respondent Answer
Jet Brigitte Vachon 1 float
Electron Ricardo Goncalo 10 floats
Photon Valeria Perez  
Tau Olya Igonkina 15 floats, 6 ints, 4 bool, 1 string
Muon Margherita Primavera L2-muIso 5 float, 5 int : EF-Moore 3 float, 1 int : EF-muid 3 float, 2 int : EF-comb 8 float, 2 int, 3 long
MET Martine Bosman  
Minbias William Bell  
Bphys Julie Kirk 3 float, 1 double
Bjet Andrea Coccaro 9 floats
Cosmic Jamie Boyd
