[Jet Offset vs bunch position in simulation]

Offset in jet transverse energy ETjet in simulation as a function of the distance from the last empty bunch (DFE) in the current bunch train, binned in , for the central pseudo-rapidity region. is the number of interactions per bunch crossing expected from the measured luminosity, averaged over the luminosity block of the current event. Calorimeter jets reconstructed at the EM scale are associated to truth jets in a range of pTtrue . Each point shows the mean ETjet in a specific and DFE range, after subtracting the average transverse energy in the plateau region (DFE > 600 ns). For 5.5 < mu < 6.5, the maximum amplitude of the energy variation is 0.8 GeV.

[Jet Offset vs bunch position in data]

Offset in jet transverse energy ETjet in data as a function of the distance from the last empty bunch (DFE) in the current bunch train, binned in , for the central pseudo-rapidity region. is the number of interactions per bunch crossing expected from the measured luminosity, averaged over the luminosity block of the current event. Calorimeter jets reconstructed at the EM scale are associated to track jets in a range of ptTrackjet . Each point shows the most probable value of ETjet in a specific and DFE range, after subtracting the average transverse energy in the plateau region (DFE > 600 ns). For 5:5 < mu < 6:5, the maximum amplitude of the energy variation is 1.5 GeV. eps file png file
