  1. JetMET Trigger Plans Leonard Apanasevich University of Illinois at Chicago apana@fnal.gov

  2. Outline • Overview of upcoming trigger planning activities • Physics priorities during initial commissioning stage • Trigger Coordination Group structure Leonard Apanasevich

  3. Higher Level Trigger Activities • Implement regional unpacking in all subsystems • Example: substantial reduction in regional ECAL unpacking for  + e/ • Code is available for siStrip, other systems pending • Optimization • Code improvement, accept time-outs (600 ms) • Algorithms • Complementary triggers • Control samples • Trigger Menus • Initial trigger menus  • Thresholds, prescales • Trigger DQM • Next Milestone: • Physics-Trigger Week,October 22 - 26 Wesley Smith Mike Lamont, 20.06.07: Phase A Buildup Leonard Apanasevich

  4. Simulated L1 rates at 1028 • No thresholds other than noise suppression needed at L = 1028-1029 for all triggers: muons, e/, jets, missing ET, HT Plot made using 10 million minbias events - no pileup (from S. Dasu) Leonard Apanasevich

  5. Physics Priorities for Phase A • Calibrate the detector • Begin to re-establish the Standard Model • Minbias PT and Rapidity Distributions • Study Jet Angular Distribution, DiJets • Establish MET • Gamma + Jet Calibration • Standard Candles: J/Ψ, Υ, W, Z Leonard Apanasevich

  6. Trigger Coordination Organigram Leonard Apanasevich

  7. TSG Needs You! Volunteers needed from POGs/PAGs/DPG’s • Trigger Menu Development • Study rates and prescale factors • Measure efficiencies • HLT Algorithm Development • Implement and maintain HLT paths • Trigger Menu Implementation • Study misalignment/miscalibration effects • Trigger Performance • Trigger Validation • Write DQM monitoring software • Evaluate CPU/memory usage Leonard Apanasevich

  8. Priorities for JetMET • Need a volunteer to prepare release validation plots • L1 and HLT rates and efficiencies for our base triggers • Eventually migrate these into the DQM infrastructure • Begin studying misalignment/miscalibration effects • Alignment and calibration scenarios based upon 10 pb-1 and 100 pb-1 of data in place for most sub-systems. • Implement regional unpacking/reco for jets Leonard Apanasevich
