Cutflows with test cuts:

• The following SR cuts are used:
  1. All events
  2. GRL: data12_8TeV.periodAllYear_DetStatus-v61-pro14-02_DQDefects-00-01-00_PHYS_StandardGRL_All_Good.xml
  3. Trigger EF_xe80_tclcw
  4. Primary vertex with >= 2 tracks
  5. Bad events cleaning (tileError, larError, coreFlags&0x40000) no TileTripReader requirement
  6. Jet cleaning( remove events with any bad jet ("looser") with pT > 20 GeV.
  7. Leading jet pT > 120 GeV and |eta| < 2.0
  8. Leading jet cleaning: chf > 0.1*fmax
  9. MET > 150 GeV using MET_Egamma10NoTau recalculated with MissingETUtility without muon term (see below).
  10. min(DeltaPhi(MET, jets)) > 0.5 (jets are defined with pT>30 GeV and |eta|<2.8)
  11. Electron veto (mediumPP, pT>20 GeV, |η|<2.47, author 1 or 3, no badclus)
  12. Muon veto (combined or segment-tagged, pT>10 GeV, |η|<2.5 ptCone20/pt<0.1, pass MCP track cuts)
  13. Njet < 3 where jet is pT > 30 GeV, |eta| < 2.8

• Overlap removal with muons and electrons is applied after the VeryLooseBad cleaning.
  1. remove jet (pT>20 GeV) if dR<0.2 with an electron.
  2. remove the lepton (as defined in 11, 12) if dR<0.4 between the lepton and a jet (pT>20 GeV).

• After the overlap removal, jets are defined with pT>30 GeV and |eta|<2.8.

• MET calculation using SUSY Tools and MissingETUtility, example code:

     SUSYObjDef::SUSYObjDef* m_susy_obj = new SUSYObjDef::SUSYObjDef();
     m_susy_obj->initialize(isData, isAtlfast); //--- See the code in SUSYTools for the options
     METUtility* met_util =  m_susy_obj->GetMETUtility();  

     met_util->defineMissingET( ... ); // Set false the muon term and the tau term. 
      
      TVector2 met_vec;
      met_vec = m_susy_obj->GetMET( ... );  //  See the code in SUSYTools for the arguments.

• For the Wmunu CR:
  1. SR selection 1 to 11.
  2. exactly one muon with same quality as in SR
  3. 40 GeV < mT < 100 GeV
  4. Njet < 3 where jet is pT > 30 GeV, |eta| < 2.8

• The mT variable is defined using the MET object calculated above and the selected muon:

          Float_t metX=0, metY=0;
          metX = met_vec.X();
          metY = met_vec.Y();
 
          TVector2 met_muon;
          met_muon.Set(metX - muon_px, metY - muon_py);
          Float m_MT = sqrt( 2*met_muon.Mod()*muon_pt*( 1-cos( deltaPhi(  muon_phi, met_muon.Phi() ))));

• For the Wenu CR:
  1. SR selection 1 to 10 + Muon veto (electron-jet overlap removal should have been applied before)
  2. (12.) At least one electron with same quality as in SR
  3. (13.) Njet < 3 where jet is pT > 30 GeV, |eta| < 2.8

• The electrons, muons and jet are properly calibrated according to the official recommendations

• The samples used is the data run 201556, as provided by the following susy d3pd: data12_8TeV.00201556.physics_JetTauEtmiss.merge.NTUP_SUSYSKIM.r4065_p1278_p1328_p1329/
