First look at W production using AOD’s UK e/gamma Meeting, May 2005 Graham Kilvington Royal Holloway, University of London 1 5/5/5
Overview: • Using Athena PhysicsAnalysis package to perform AOD analysis • Running code over W → e νAODs (generated using release 10.0.1), available from: /castor/cern.ch/user/m/mwielers/test1001/AOD • My analysis using this package has just begun: reporting on current status of work 2 5/5/5
AOD variables: • Event variables accessed from AOD: 3 5/5/5
AOD variables: • Event variables accessed from AOD: 4 5/5/5
AOD variables: • Event variables accessed from AOD: 5 5/5/5
Plotting the W mass: • W-mass: • Cuts: • ETelectron > 25 GeV • ETMissing > 18 GeV 6 5/5/5
Plotting the W mass: • W-mass: • From TDR: 7 5/5/5
Plans from here: • Incorporate SUSYPhys package into my Athena setup – contains many useful functions • Use AOD truth info to look into SUSY cut selection efficiencies 8 5/5/5
