DSG without any njet cuts and without Z veto

  • removed Z veto and 2nd Z cut
  • important: Z window dependent MET cut not corrected

  • Motivation: susy signal after step at around 75 GeV in Paris' susy analysis

Reduce SM background to 10% and 1 % of itself

  • MET: hyp_met
  • SumEt : sum of all jetEt for jets with pTjet > 15 GeV and eta < 3.0

WW baseline without caloJet=0 and trkJet=0 cuts, no Z cuts
