  4. MC truth event selections Select 2l2n events at MC truth level: mono-Z: qq->Znn, Z->ee/mm/tt SM ZZ: qq->ZZ->llnn Z mass line shape with following filter: D1,D5,D9: |mll - mZ| < 37 GeV (Madgraph, ATLFAST II) D10: zero width approximation (Madgraph, ATLFAST II) SM ZZ: mll > 4 GeV (Powheg+pythia8) Use a preselection for the kinematics comparison |mll-mZ| < 25 GeV 4 12/14/201211/30/2012 Lailin Xu

  9. Summary Kinematics comparison among different DM model operators with the SM ZZ background Discussion: Only ALTFAST (II) simulations, should we produce full simulation samples ? Not enougth statisics: D1/D5/D9: 10k; D10: 5K 9 12/14/201211/30/2012 Lailin Xu
