Selections • Triggers HLT_Mu17_Mu8_v* HLT_Mu17_TkMu8_v* • Muon Muon matched trigger objects Muon pT > 20 GeV and |Muon eta| < 2.4 Opposite charge muons Tight Muon ID from Muon POG Loose PF base Combined relative ISO from Muon POG Z mass window of 71 to 111 GeV • PF Jet PF Jet pT > 30 GeV PFnoPU Compare Z+ only 1 jet in HF (|eta| >2.4) veto events that have jet in Barrel and Endcap Loose Jet ID from POG Clean Jets from muons with DeltaR<0.5 • Calo Jet Match Calo jet to PF jet with DeltaR < 0.5 Loose calo jet ID
Notes • These plots are from all 2012 rereco data in the total of 19.62 fb-1. • We are working on new cuts in Z+jets X-section analysis. The new cuts will be used in the next release (Still on the discussion). • I picked Z+1PF jet in HF first before matching this PF jet to a calo jet with dR<0.5. • This is only from Z(mumu)+1 PF jet in HF.
