  1. Objects (See https://twiki.cern.ch/twiki/pub/Atlas/SusyCscNote5/objectdefinition.v2.pdf ) • electron: egamma (author 1 or 3), isEM_mask=0x3ff, etcone20<10GeV, pT>20GeV, |eta|<2.5, dR(e-j)>0.4 • electron for crack veto: egamma (author 1 or 3), isEM_mask=0x3ff, pT>10GeV, 1.52>|eta|<1.37 • muon: combined STACO muon (with bestMatch), 0<matchChi2<100, etcone20<10GeV, pT>20GeV, |eta|<2.5, dR(mu-j)>0.4 • lepton for 2nd lepton veto: standard lepton ID(above) with 20GeV>pT>10GeV • jet: Cone4TowerParticleJets, |eta|<2.5, pT>20GeV, far from electron dR=0.2 • jet for dR(lep-j)>0.4: standard jets without eta cut • missing: MET_RefFinal, MET_RefFinal_1mmCorrection for correction samples • Definition • effective mass(Meff): missingET + jet1 + jet2 + jet3 + jet4 + one lepton • transvers sphericity(TS): input=all jets (above definition) and one lepton • Event selection • no electron(>10GeV) in crack region(1.37-1.52) • one lepton (electron or muon>20GeV) • no second lepton (10-20GeV) • at least 4 jets • jet1 > 100GeV • jet4 > 50GeV • missing ET > 100GeV • missing ET > 0.2*Meff • TS > 0.2 • MT(transvers mass) > 100GeV
