## 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

...

### ESD

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

### AOD

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

### DPD

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 T2CaloTau: 4 float T2IDTau: 3 float, 8 int, 3 bool T2Tau: 1 float, 4 int EFTau: 5 float, 2 int, 1 bool Muon Margherita Primavera L2-mufast: 8 float, 3 int L2-mucomb: 6 float 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
