Stan Bentvelsen - NIKHEF P 5 Samples for Rome 10 M background sample  Event sample Defined by MC group (Ian) – weekly meetings I am contact person Top group  Simulation with release 8.8.x Plan to simulate over Xmas  Reconstruction with release 9.0.x Avaliable from approx February 1 M ‘signal’ sample for each physics group  Free to define ourselves!

Stan Bentvelsen - NIKHEF P 7 10 M samples - notes All done with initial Altas layout  These form primary samples for Rome  Not use the DC2 events – only for ‘testing’ your analysis on AOD Very unclear who is producing the simulation  Ongoing discussion with Ian/Dario  We might need help from YOU Note that for Rome we have semi-leptonic decays only  with electron, muon, tau Background done with Sherpa (?)

Stan Bentvelsen - NIKHEF P 8 Our 1 M sample Various scenarios possible  ttbar events with TopRex (Pythia) to include spin correlations (0.6M)  Single top events using TopRex (0.4M)  Di-lepton sample (included in toprex) We need to define this (if we want to use them..)  Who?  Interest from Nikhef for single top We need to run the GRID jobs!

Stan Bentvelsen - NIKHEF P 9 Remark I strongly advocate to use the ESD/AOD as presented by Ketevi  Who is extending the common top-example that Ketevi started? We should use and analyse these fully simulated events  Bottle of wine for the first analysis presented in this top group done on AOD
