Jet Uncertainties

Abstract
The JES calibration scheme detailed in Sect. 4.3 consists of several steps, and thus systematic biases can be introduced in many places during the derivation. The in situ analyses measure the uncertainties with respect to \(p_\mathrm {T}^{\mathrm {jet}}\) and \(\eta \) by quantifying the calorimeter jet response differences observed between data and simulation in well-understood topologies. This accounts for the majority of the possible differences. Additional systematic uncertainties accounting for the MC simulation framework used (such as GEANT4 or AFII), pileup suppression modelling, flavour dependencies, and punch-through are also independently evaluated.
