  1. VBF Htt report Catalin & Tony April 24, 2007

  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:
