L1Offset tranvserse momentum correction for AK5 PFJets as a function of jet pseudorapidity in data (black) and Monte Carlo (green). Different intervals of reconstructed primary vertices (N_{PV}) are shown with different markers.

MC-Truth L2L3 corrections for AK5 PFJets as a function of jet pseudorapidity for three reference transverse momentum values: 30 GeV (white hollow circles), 100 GeV (red squares) and 300 GeV (blue circles).

L2 Residual corrections, obtained on dijet events, for AK5 PF charged-hadron-subtracted (CHS) jets, as a function of jet pseudorapidity. The JES uncertainty, taken at the representative transverse momentum value of 100 GeV is shown with a blue band, while the statistical uncertainty is shown with a yellow band.

L3 residual correction in Z->mumu events, for AK5 PFCHS jets reconstructed in the center of the barrel (eta<1.3) and corrected with the full chain of corrections (L1, L2L3, L2 residuals and L3 residuals). The extrapolation as a function of the relative second jet transverse momentum is shown for the main MPF method (red/brown markers) and the backup pT balancing method (blue/black markers). Data is shown with circular markers, MC with stars.

Data/MC ratio of the trends shown in the above plot: MPF response extrapolation shown in red, pT balancing shown in blue. The trends are fitted with a first degree polinomial and the value of the fitted intercept is shown in the bottom right part of the plot. The statistical compatibility with unity ensures that the L3 residuals are adeguate.

MC-truth response for AK5 PF jets reconstructed in the center of the barrel originated from partons of different flavor: bottom quarks (red), charm quarks (green), gluons (blue) and light quarks (yellow). The response for the QCD flavor mixture is also shown in black: the fact that it is close to unity across the momentum interval is proof of good closure.

Jet energy correction uncertainties as a function of jet transverse momentum for jets reconstructed around eta = 0. Different contributions are shown with markers of different colors, and the total uncertainty is shown with a grey band.

Jet energy correction uncertainties as a function of jet transverse momentum for jets reconstructed around eta = 2.0. Different contributions are shown with markers of different colors, and the total uncertainty is shown with a grey band.

Jet energy correction uncertainties as a function of jet transverse momentum for jets reconstructed around eta = 2.7. Different contributions are shown with markers of different colors, and the total uncertainty is shown with a grey band.

Jet energy correction uncertainties as a function of jet pseudorapidity for jets with transverse momentum equal to 30 GeV. Different contributions are shown with markers of different colors, and the total uncertainty is shown with a grey band.

Jet energy correction uncertainties as a function of jet pseudorapidity for jets with transverse momentum equal to 100 GeV. Different contributions are shown with markers of different colors, and the total uncertainty is shown with a grey band.

Jet energy correction uncertainties as a function of jet pseudorapidity for jets with energy equal to 1000 GeV. Different contributions are shown with markers of different colors, and the total uncertainty is shown with a grey band.
