  1. Some Thoughts on Systematic Uncertainties in the Determination of the Jet Energy Scale Calorimeter response Model (e.g. QGSP vs EMV) Jet Composition And Fragmentation Model Jet Location

  3. Other Contributors: Anything we use to correct the response • GEANT4 model for energy deposition • Charged particle fraction • EM fraction by depth • Numerical method (inversion) • Jet Isolation cut • Cut on additional jets (ISR/FSR model) • Out-of-Cone energy (offset not a scale) • Underlying event energy (offset not a scale, and process dependent) • In-time pileup • Bunch structure • Luminosity dependence within runs
