Description
The reconstruction and calibration of hadronic final states is an extremely challenging experimental aspect of measurements and searches at the LHC. This talk summarizes the latest results from ATLAS for jet reconstruction and calibration of Anti-kt R=0.4 jets. New approaches to jet inputs better utilize relationships between calorimeter and tracking information to significantly improve the jet performance in preparation for Run-3. Additionally, new pile-up mitigation techniques are shown to provide a better stability with respect to pile-up. Finally, new jet calibration methods are presented, which reduce the uncertainties in the high pileup conditions of the LHC Run 2.
