BG study in PAT CMSSW_3_5_7
All of these using this event selection
Event Selection - Electron pT > 20 GeV/c - Electron Isolation < 0.1 - Standard Electron Identification - Electron abs(eta) < 2.5 - Missing Transverse Energy > 20 GeV - At least 3 jets with Pt(L2L3) > 20 GeV - At least one of above jets is b (>2.03)
M(jj) Reconstruction - Jet pT > 25 GeV/c - HighEfficenecy b tag < 2.03 - abs(eta) <3 - ΔR(jj) > 0.5
Data set: /ZeeJet_Pt30to50/Spring10-START3X_V26_S09-v1/GEN-SIM-RECO
*With L2L3 energy correction*Add 2 more event selections At least 3 jets with Pt(L2L3) > 20 GeV and At least one of above jets is b (>2.03)* Change Jet Pt to > 25 GeV/c
