  2. t-tbar fully hadronic decay samples 5204 • CSC11 AODs • csc11.005204.TTbar_FullHad_McAtNlo_Jimmy.recon.AOD.v11004205 • DC3-02 • MC@NLO 3.1 • 285 files, 275 550 events • CSC12 AODs • trig1_misal1_mc12.005204.TTbar_FullHad_McAtNlo_Jimmy.recon.AOD.v12000601_tid006015 • CSC-01-02-00 • MC@NLO 3.1 • 298 files, 73 950 events • We only looked at jets • first look at comparison... sample 5204 CSC 11 and 12

  11. W and top mass: Cone4 TruthJets mean mass CSC11: 78.31 ± 0.03 GeV CSC12: 78.28 ± 0.07 GeV mean mass CSC11: 163.7 ± 0.06 GeV CSC12: 163.8 ± 0.1 GeV fully hadronic t-tbar events 5204 with at least 6 jets in || < 3 6 jet-parton matched 1 to 1 same masses as expected sample 5204 CSC 11 and 12

  12. Summary TruthJets • Comparison between CSC11 and CSC12 • Jet multiplicity higher in CSC12 for Cone4 and 7 • different jet ET thresholds... • then CSC12 has a greater number of soft and central jets. • the phi distributions have been verified to be flat • The 6 highest ET jets have very similar distributions • except perhaps for the lowest ET Cone7 jets • The W and top mass reconstructed with 1 to 1 matched jet-partons are the same (within statistics) as expected sample 5204 CSC 11 and 12

  22. Summary TowerJets • Comparison between CSC11 and CSC12 • Jet multiplicity higher in CSC12 for Cone4 and 7 • different jet ET thresholds • more pronounced for Cone7 • but less pronounced than for TruthJets • For Cone4, the agreement between CSC11 and 12 for the other distributions is remarkable • The phi distributions have been verified to be flat • For Cone 7, The 6 highest ET jets have similar distributions, except for the lowest ET jets • The W and top mass reconstructed with 1 to 1 matched jet-partons are higher for CSC12 • +2.4% for W mass • +1.9% for the top mass sample 5204 CSC 11 and 12
