First loot at Jetplots of 7TeV collision

Configuration

  • CMSSW_3_5_6
  • Package
  • Data : /MinimumBias/Commissioning10-Apr1Skim_GOODCOLL-v1/RAW-RECO, Run:132440(cff) #events: around 221,000
    • Skim condition (Good collision)
      • process.L1T1coll.L1SeedsLogicalExpression = cms.string('0 AND (40 OR 41) AND NOT (36 OR 37 OR 38 OR 39) AND NOT ((42 AND NOT 43) OR (43 AND NOT 42))' )
      • Primary vertex: cut = cms.string("!isFake && ndof > 4 && abs(z) <= 15 && position.Rho <= 2"), # tracksSize() > 3 for the older cut
      • FilterOutScraping?
    • MC : /MinBias/Spring10-START3X_V25B_356ReReco-v1/GEN-SIM-RECO(cff) #events: around 226,000
  • Cut conditions
    • Inclusive Jets
      • pT>10GeV, -2.6 < eta < 2.6
    • Clean Jets (using JetID?)
      • 0.01 < emf < 0.98, fRBX < 0.98, fHPD < 0.98

Electromagnetic energy fraction

The number of Selected events, which must have jets, and jets And ratio of them

Data Set Condition Selected events ratio Selected jets ratio * No Event ratio
MC GOODCOLL 178423 1 906923 1 0.193
GOODCOLL+PtEta 1555 0.0087 1804 0.0020
GOODCOLL+PtEta+CleanJet 1353 0.8701 1570 0.8703
Data GOODCOLL 194697 1 1146253 1 0.138
GOODCOLL+PtEta 1364 0.0070 1560 0.0014
GOODCOLL+PtEta+CleanJet 1030 0.7551 1195 0.7660

  • No Event ratio = {# events(have not any jet)} / {total input events}

Result of Jet Correction using 7TeV era
