Jet Energy Scale: In-situ Calibration Strategies
This note outlines procedures for the in-situ determination of the jet energy scale and resolution of the ATLAS calorimeters. The jet energy scale is evaluated using energy-balanced processes: gamma/Z+jet, dijet, and multijet events. The jet energy resolution is obtained from dijet events. Generator...

| Sumario: | This note outlines procedures for the in-situ determination of the jet energy scale and resolution of the ATLAS calorimeters. The jet energy scale is evaluated using energy-balanced processes: gamma/Z+jet, dijet, and multijet events. The jet energy resolution is obtained from dijet events. Generators using leading-order multiparton matrix element calculations merged with parton showers along with leading-logarithmic Monte Carlo models are compared. Effects on the energy-balance due to hadronization effects are also studied. |
