LVL2 Rates and AOD Development Update - April 24, 2007

In the meeting on April 24, 2007, Catalin and Tony discussed the implementation of LVL2 rates and AOD requirements for dijet and Higgs analyses. Monika Wielers highlighted the need for modifications for earlier versions beyond 12.0.6. The team assessed Francesca Sarri's ntuples, which capture essential trigger information for manual LVL requirements. Progress on coding the LVL2-FTK requirements is ongoing. Preliminary results from dijet samples were shared, showing various event counts across different pT ranges. Future meetings aim to transport tracking code and obtain more comprehensive AODs.

  2. Default-LVL2 rates • Monika Wielers pointed us to AOD->ntuple example: • Works in 12.0.6, needs modifications for earlier versions • So we moved to 12.0.6. Will need the AOD’s for dijet and Higgs • In the meantime, Francesca Sarri pointed us to her own ntuples, which have only a fraction of the trigger information • These variables seem sufficient for a manual implementation of the LVL1/LVL2/EF requirements. • Coding the ‘LVL2-FTK’ requirements in progress, but not working quite yet. • For the next meeting we plan to: • Transport our tracking req. code to the new ntuple environment, and • get signal and background AOD’s and run athena to get official-style ntuples. Larger in size but also more complete.

  3. Very preliminary results • Dijet samples: • J0 5009 sample (dijet pT range 8-17 GeV) : 115000 evts. • J1 5010 sample (dijet pT range 17-35 GeV) : 270000 evts. • J2 5011 sample (dijet pT range 35-70 GeV) : 6000 evts. • J3 5012 sample (dijet pT range 70-140 GeV) : 9630 evts. • Francesca does not have the dijet trigger rates in her talk, but rather points to a T&P talk by Eric Torrence: http://indico.cern.ch/getFile.py/access?contribId=142&sessionId=0&resId=0&materialId=slides&confId=12404 • Comparison to Eric’s values for single tau15i trigger shows 10-20% smaller L1/L2/EF rates:
