5 Samples for Rome n 10 M background sample ¡ Event sample n n ¡ Simulation with release 8. 8. x n ¡ Plan to simulate over Xmas Reconstruction with release 9. 0. x n n Defined by MC group (Ian) – weekly meetings I am contact person Top group Avaliable from approx February 1 M ‘signal’ sample for each physics group ¡ Free to define ourselves!

7 10 M samples - notes n All done with initial Altas layout ¡ ¡ n Very unclear who is producing the simulation ¡ ¡ n Ongoing discussion with Ian/Dario We might need help from YOU Note that for Rome we have semi-leptonic decays only ¡ n These form primary samples for Rome Not use the DC 2 events – only for ‘testing’ your analysis on AOD with electron, muon, tau Background done with Sherpa (? ) Stan Bentvelsen - NIKHEF
8 Our 1 M sample n Various scenarios possible ¡ ¡ ¡ n We need to define this (if we want to use them. . ) ¡ ¡ n ttbar events with Top. Rex (Pythia) to include spin correlations (0. 6 M) Single top events using Top. Rex (0. 4 M) Di-lepton sample (included in toprex) Who? Interest from Nikhef for single top We need to run the GRID jobs! Stan Bentvelsen - NIKHEF
9 Remark n I strongly advocate to use the ESD/AOD as presented by Ketevi ¡ n 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 Stan Bentvelsen - NIKHEF
