A determination of the jet energy scale is presented using proton–proton collision data with a centre-of-mass energy of s=13s ​=13 TeV, corresponding to an integrated luminosity of 140 fb−1−1 collected using the ATLAS detector at the LHC. Jets are reconstructed using the ATLAS particle-flow method that combines charged-particle tracks and topo-clusters formed from energy deposits in the calorimeter cells. The anti-ktkt​ jet algorithm with radius parameter R=0.4R=0.4 is used to define the jet. Novel jet energy scale calibration strategies developed for the LHC Run 2 are reported that lay the foundation for the jet calibration in Run 3. Jets are calibrated with a series of simulation-based corrections, including state-of-the-art techniques in jet calibration such as machine learning methods and novel in situ calibrations to achieve better performance than the baseline calibration derived using up to 81 fb−1−1 of Run 2 data.
